A search for high-mass charged and neutral bosons decaying to Wγ and Zγ final states is presented in this paper. The analysis uses a data sample of s = 13 TeV proton-proton collisions with an integrated luminosity of 139 fb⁻¹ collected by the ATLAS detector during LHC Run 2 operation. The sensitivity of the search is determined using models of the production and decay of spin-1 charged bosons and spin-0/2 neutral bosons. The range of resonance masses explored extends from 1.0 TeV to 6.8 TeV. At these high resonance masses, it is beneficial to target the hadronic decays of the W and Z bosons because of their large branching fractions. The decay products of the high-momentum W/Z bosons are strongly collimated and boosted-boson tagging techniques are employed to improve the sensitivity. No evidence of a signal above the Standard Model backgrounds is observed, and upper limits on the production cross-sections of these bosons times their branching fractions to Wγ and Zγ are derived for various boson production models.

Preliminary focal mechanism pattern along the central part of the Great Sumatran Fault, Indonesia

引用

AIP Conference Proceedings 2018年第1期1987卷

作者： Alief Rizky Ramadhan Dian Kusumawati David P. Sahara Sri Widiyantoro 1Geophysical Engineering Study Program Faculty of Petroleum and Mining Engineering Bandung Institute of Technology Jl. Ganesha 10 Bandung 40132 Indonesia 2Earth Sciences Study Program Faculty of Earth Sciences and Technology Bandung Institute of Technology Jl. Ganesha 10 Bandung 40132 Indonesia 3Global Geophysics Research Group Faculty of Petroleum and Mining Engineering Bandung Institute of Technology Jl. Ganesha 10 Bandung 40132 Indonesia

According to the world stress map, the regional in-situ stress along the Great Sumatran Fault (GSF) is assumed to be strike-slip, and the maximum principal stress (SHmax) is oriented toward N15°E. However, this was estimated from limited global focal mechanisms available along the GSF. A larger dataset of focal mechanisms along the GSF is required to revise the solution and infer the local stress perturbation. To create a new focal mechanism catalogue of local events, we worked on waveform data from a joint seismic network of 35 stations deployed by the Indonesian Agency for Meteorology, Climatology, and Geophysics (BMKG) and the GeoForschungZentrum (GFZ) Germany. The seismic network has a full coverage of the Sumatran fault. From October 2008 to February 2017, there were 476 events with magnitude (Mw) greater than 3 and focal depth shallower than 100 km that occurred in the central part of GSF. Arrival time picking of P and S waves and polarity identification were performed manually using Seisgram. The polarity of P waves was then used to obtain the focal mechanism of the events in the 4 segments of GSF branches (Northwest, Southwest, Northeast, and Southeast). The new local focal mechanism catalogue can be used, together with the global one, to invert the detailed stress heterogeneity in the study area.

A search for proton decay into e+/µ+ and a η meson has been performed using data from a 0.373 Mton·year exposure (6050.3 live days) of Super-Kamiokande. Compared to previous searches this work introduces an improved model of the intranuclear η interaction cross section, resulting in a factor of two reduction in uncertainties from this source and ∼10% increase in signal efficiency. No significant data excess was found above the expected number of atmospheric neutrino background events resulting in no indication of proton decay into either mode. Lower limits on the proton partial lifetime of 1.4 × 1034 years for p → e+η and 7.3 × 1033 years for p → µ+η at the 90% C.L. were set. These limits are around 1.5 times longer than our previous study and are the most stringent to date. © 2024, CC BY.

The first evidence for the Higgs boson decay to a Z boson and a photon is presented, with a statistical significance of 3.4 standard deviations. The result is derived from a combined analysis of the searches performed by the ATLAS and CMS Collaborations with proton-proton collision datasets collected at the CERN Large Hadron Collider (LHC) from 2015 to 2018. These correspond to integrated luminosities of around 140 fb−1 for each experiment, at a center-of-mass energy of 13 TeV. The measured signal yield is 2.2±0.7 times the standard model prediction, and agrees with the theoretical expectation within 1.9 standard deviations.

Silicon photomultipliers (SiPMs) have become the baseline choice for cameras of the small-sized telescopes (SSTs) of the Cherenkov Telescope Array (CTA). On the other hand, SiPMs are relatively new to the field and covering large surfaces and operating at high data rates still are challenges to outperform photomultipliers (PMTs). The higher sensitivity in the near infra-red and longer signals compared to PMTs result in higher night sky background rate for SiPMs. However, the robustness of the SiPMs represents a unique opportunity to ensure long-term operation with low maintenance and better duty cycle than PMTs. The proposed camera for large size telescopes will feature 0.05◦ pixels, low power and fast front-end electronics and a fully digital readout. In this work, we present the status of dedicated simulations and data analysis for the performance estimation. The design features and the different strategies identified, so far, to tackle the demanding requirements and the improved performance are described. Copyright © 2021, The Authors.

The Large-Sized Telescope (LST) prototype of the future Cherenkov Telescope Array (CTA) is located at the Northern site of CTA, on the Canary Island of La Palma. It is designed to provide optimal performance in the lowest part of the energy range covered by CTA, observing gamma rays down to energies of tens of GeV. The LST prototype started performing astronomical observations in November 2019 during the commissioning of the telescope and it has been taking data since then. In this contribution, we will present the tuning of the characteristics of the telescope in the Monte Carlo (MC) simulations to describe the data obtained, the estimation of its angular and energy resolution, and an evaluation of its sensitivity, both with simulations and with observations of the Crab Nebula. © 2021, CC BY.

ALICE is a large experiment at the CERN Large Hadron Collider. Located 52 meters underground, its detectors are suitable to measure muons produced by cosmic-ray interactions in the atmosphere. In this paper, the studies of the cosmic muons registered by ALICE during Run 2 (2015–2018) are described. The analysis is limited to multimuon events defined as events with more than four detected muons (N_µ > 4) and in the zenith angle range 0^◦ < θ < 50^◦. The results are compared with Monte Carlo simulations using three of the main hadronic interaction models describing the air shower development in the atmosphere: QGSJET-II-04, EPOS-LHC, and SIBYLL 2.3d. The interval of the primary cosmic-ray energy involved in the measured muon multiplicity distribution is about 4×10¹⁵ < E_prim < 6×10¹⁶ eV. In this interval none of the three models is able to describe precisely the trend of the composition of cosmic rays as the energy increases. However, QGSJET-II-04 is found to be the only model capable of reproducing reasonably well the muon multiplicity distribution, assuming a heavy composition of the primary cosmic rays over the whole energy range, while SIBYLL 2.3d and EPOS-LHC underpredict the number of muons in a large interval of multiplicity by more than 20% and 30%, respectively. The rate of high muon multiplicity events (N_µ > 100) obtained with QGSJET-II-04 and SIBYLL 2.3d is compatible with the data, while EPOS-LHC produces a significantly lower rate (55% of the measured rate). For both QGSJET-II-04 and SIBYLL 2.3d, the rate is close to the data when the composition is assumed to be dominated by heavy elements, an outcome compatible with the average energy E_prim ∼ 10¹⁷ eV of these events. This result places significant constraints on more exotic production mechanisms. © 2025 The Author(s).
