this paper describes the first all-sky search for long-duration, quasimonochromatic gravitational-wave signals emitted by ultralight scalar boson clouds around spinning black holes using data from the third observing run of Advanced LiGO. We analyze the frequency range from 20 to 610 Hz, over a small frequency derivative range around zero, and use multiple frequency resolutions to be robust towards possible signal frequency wanderings. Outliers from this search are followed up using two different methods, one more suitable for nearly monochromatic signals, and the other more robust towards frequency fluctuations. We do not find any evidence for such signals and set upper limits on the signal strain amplitude, the most stringent being ≈10−25 at around 130 Hz. We interpret these upper limits as both an “exclusion region” in the boson mass/black hole mass plane and the maximum detectable distance for a given boson mass, based on an assumption of the age of the black hole/boson cloud system.

the paper presents a search for supersymmetric particles produced in proton-proton collisions at $$ \sqrt{s} $$ = 13 teV and decaying into final states with missing transverse momentum and jets originating from charm quarks. the data were taken with the AtLAS detector at the Large Hadron Collider at CERN from 2015 to 2018 and correspond to an integrated luminosity of 139 fb−1. No significant excess of events over the expected Standard Model background expectation is observed in optimized signal regions, and limits are set on the production cross-sections of the supersymmetric particles. Pair production of charm squarks or top squarks, each decaying into a charm quark and the lightest supersymmetric particle $$ {\overset{\sim }{\chi}}_1^0 $$ , is excluded at 95% confidence level for squarks with masses up to 900 GeV for scenarios where the mass of $$ {\overset{\sim }{\chi}}_1^0 $$ is below 50 GeV. Additionally, the production of leptoquarks with masses up to 900 GeV is excluded for the scenario where up-type leptoquarks decay into a charm quark and a neutrino. Model-independent limits on cross-sections and event yields for processes beyond the Standard Model are also reported.

A measurement of the ratio of the branching fractions, Rτ/e = B(W → τν)/B(W → eν), is performed using a sample of W bosons originating from top-quark decays to final states containing τ-leptons or electrons. this measurement uses pp collisions at $$ \sqrt{s} $$ = 13 teV, collected by the AtLAS experiment at the Large Hadron Collider during Run 2, corresponding to an integrated luminosity of 140 fb−1. the W → τντ (with τ → eνeντ) and W → eνe decays are distinguished using the differences in the impact parameter distributions and transverse momentum spectra of the electrons. the measured ratio of branching fractions Rτ/e = 0.975 ± 0.012 (stat.) ± 0.020 (syst.), is consistent with the Standard Model assumption of lepton flavour universality in W-boson decays.

An analysis of solar neutrino data from the fourth phase of super-Kamiokande (sK-iV) from October 2008 to May 2018 is performed and the results are presented. the observation time of the dataset of sK-iV corresponds to 2970 days and the total live time for all four phases is 5805 days. For more precise solar neutrino measurements, several improvements are applied in this analysis: lowering the data acquisition threshold in May 2015, further reduction of the spallation background using neutron clustering events, precise energy reconstruction considering the time variation of the PMt gain. the observed number of solar neutrino events in 3.49–19.49 MeV electron kinetic energy region during sK-iV is 65,443−388+390(stat.)±925(syst.) events. Corresponding B8 solar neutrino flux is (2.314±0.014(stat.)±0.040(syst.))×106 cm−2 s−1, assuming a pure electron-neutrino flavor component without neutrino oscillations. the flux combined with all sK phases up to sK-iV is (2.336±0.011(stat.)±0.043(syst.))×106 cm−2 s−1. Based on the neutrino oscillation analysis from all solar experiments, including the sK 5805 days dataset, the best-fit neutrino oscillation parameters are sin2θ12,solar=0.306±0.013 and Δm21,solar2=(6.10−0.81+0.95)×10−5 eV2, with a deviation of about 1.5σ from the Δm212 parameter obtained by KamLAND. the best-fit neutrino oscillation parameters obtained from all solar experiments and KamLAND are sin2θ12,global=0.307±0.012 and Δm21,global2=(7.50−0.18+0.19)×10−5 eV2.

Japan Astrometry satellite Mission for iNfrared Exploration (JAsMiNE) is a planned M-class science space mission by the institute of space and Astronautical science, the Japan Aerospace Exploration Agency. JAsMiNE has two main science goals. One is the Galactic archaeology with Galactic Center survey, which aims to reveal the Milky Way's central core structure and formation history from Gaia-level (∼25 µas) astrometry in the Near-infrared (NiR) Hw-band (1.0-1.6 µm). the other is the Exoplanet survey, which aims to discover transiting Earth-like exoplanets in the habitable zone from NiR time-series photometry of M dwarfs when the Galactic center is not accessible. We introduce the mission, review many science objectives, and present the instrument concept. JAsMiNE will be the first dedicated NiR astrometry space mission and provide precise astrometric information of the stars in the Galactic center, taking advantage of the significantly lower extinction in the NiR. the precise astrometry is obtained by taking many short-exposure images. Hence, the JAsMiNE Galactic center survey data will be valuable for studies of exoplanet transits, asteroseismology, variable stars and microlensing studies, including discovery of (intermediate mass) black holes. We highlight a swath of such potential science, and also describe synergies with other missions. © 2023, CC BY.

A search for pair production of vector-like leptons coupling to first- and second-generation Standard Model leptons is presented. the search is based on a dataset of proton-proton collisions at $$ \sqrt{s} $$ = 13 teV recorded with the AtLAS detector during Run 2 of the Large Hadron Collider, corresponding to an integrated luminosity of 140 fb−1. Events are categorised depending on the flavour and multiplicity of leptons (electrons or muons), as well as on the scores of a deep neural network targeting particular signal topologies according to the decay modes of the vector-like leptons. in each of the signal regions, the scalar sum of the transverse momentum of the leptons and the missing transverse momentum is analysed. the main background processes are estimated using dedicated control regions in a simultaneous fit with the signal regions to data. No significant excess above the Standard Model background expectation is observed and limits are set at 95% confidence level on the production cross-sections of vector-like electrons and muons as a function of the vector-like lepton mass, separately for SU(2) doublet and singlet scenarios. the resulting mass lower limits are 1220 GeV (1270 GeV) and 320 GeV (400 GeV) for vector-like electrons (muons) in the doublet and singlet scenarios, respectively.

A study of the Higgs boson decaying into bottom quarks (H → $$ b\overline{b} $$ ) and charm quarks (H → $$ c\overline{c} $$ ) is performed, in the associated production channel of the Higgs boson with a W or Z boson, using 140 fb−1 of proton-proton collision data at $$ \sqrt{s} $$ = 13 teV collected by the AtLAS detector. the individual production of WH and ZH with H → $$ b\overline{b} $$ is established with observed (expected) significances of 5.3 (5.5) and 4.9 (5.6) standard deviations, respectively. Differential cross-section measurements of the gauge boson transverse momentum within the simplified template cross-section framework are performed in a total of 13 kinematical fiducial regions. the search for the H → $$ c\overline{c} $$ decay yields an observed (expected) upper limit at 95% confidence level of 11.5 (10.6) times the Standard Model prediction. the results are also used to set constraints on the charm coupling modifier, resulting in |κc| < 4.2 at 95% confidence level. Combining the H → $$ b\overline{b} $$ and H → $$ c\overline{c} $$ measurements constrains the absolute value of the ratio of Higgs-charm and Higgs-bottom coupling modifiers (|κc/κb|) to be less than 3.6 at 95% confidence level.

Results are presented for a semicoherent search for continuous gravitational waves from the low-mass x-ray binary scorpius X-1, using a hidden Markov model (HMM) to allow for spin wandering. this search improves on previous HMM-based searches of Laser interferometer Gravitational-Wave Observatory data by including the orbital period in the search template grid, and by analyzing data from the latest (third) observing run. in the frequency range searched, from 60 to 500 Hz, we find no evidence of gravitational radiation. this is the most sensitive search for scorpius X-1 using a HMM to date. For the most sensitive subband, starting at 256.06 Hz, we report an upper limit on gravitational wave strain (at 95% confidence) of h095%=6.16×10−26, assuming the orbital inclination angle takes its electromagnetically restricted value ι=44°. the upper limits on gravitational wave strain reported here are on average a factor of ∼3 lower than in the second observing run HMM search. this is the first scorpius X-1 HMM search with upper limits that reach below the indirect torque-balance limit for certain subbands, assuming ι=44°.

this paper presents the reconstruction of missing transverse momentum ( $$p_{\text {t}}^{\text {miss}}$$ ) in proton–proton collisions, at a center-of-mass energy of 13 teV. this is a challenging task involving many detector inputs, combining fully calibrated electrons, muons, photons, hadronically decaying $$\tau $$ -leptons, hadronic jets, and soft activity from remaining tracks. Possible double counting of momentum is avoided by applying a signal ambiguity resolution procedure which rejects detector inputs that have already been used. several $$p_{\text {t}}^{\text {miss}}$$ ‘working points’ are defined with varying stringency of selections, the tightest improving the resolution at high pile-up by up to 39% compared to the loosest. the $$p_{\text {t}}^{\text {miss}}$$ performance is evaluated using data and Monte Carlo simulation, with an emphasis on understanding the impact of pile-up, primarily using events consistent with leptonic Z decays. the studies use $$140~\text {fb}^{-1}$$ of data, collected by the AtLAs experiment at the Large Hadron Collider between 2015 and 2018. the results demonstrate that $$p_{\text {t}}^{\text {miss}}$$ reconstruction, and its associated significance, are well understood and reliably modelled by simulation. Finally, the systematic uncertainties on the soft $$p_{\text {t}}^{\text {miss}}$$ component are calculated. After various improvements the scale and resolution uncertainties are reduced by up to $$76\%$$ and $$51\%$$ , respectively, compared to the previous calculation at a lower luminosity.

We report on the discovery of two potential polar ring galaxies (PRGs) in the WALLABY Pilot Data Release 1 (PDR1). these untargetted detections, cross-matched to NGC 4632 and NGC 6156, are some of the first galaxies where the H i observations show two distinct components. We used the iDaViE virtual reality software to separate the anomalous gas from the galactic gas and find that the anomalous gas comprises ∼ 50% of the total H i content of both systems. We have generated plausible 3D kinematic models for each galaxy assuming that the rings are circular and inclined at 90◦ to the galaxy bodies. these models show that the data are consistent with PRGs, but do not definitively prove that the galaxies are PRGs. By projecting these models at different combinations of main disk inclinations, ring orientations, and angular resolutions in mock datacubes, we have further investigated the detectability of similar PRGs in WALLABY. Assuming that these galaxies are indeed PRGs, the detectability fraction, combined with the size distribution of WALLABY PDR1 galaxies, implies an incidence rate of ∼ 1% − 3%. if this rate holds true, the WALLABY survey will detect hundreds of new polar ring galaxies. © 2023, CC BY.
