Gaia Data Release 3 contains a wealth of new data products for the community. Astrophysical parameters are a major component of this release. They were produced by the Astrophysical parameters inference system (Apsis) within the Gaia Data Processing and Analysis Consortium. The aim of this paper is to describe the overall content of the astrophysical parameters in Gaia DR3 and how they were produced. In Apsis we use the mean bP/RP and mean RVs spectra along with astrometry and photometry, and we derive the following parameters: source classification and probabilities for 1.6 billion ob.e.ts, interstellar medium characterisation and distances for up to 470 million sources, including a 2D total Galactic extinction map, 6 million redshifts of quasar candidates and 1.4 million redshifts of galaxy candidates, along with an analysis of 50 million outlier sources through an unsupervised classification. The astrophysical parameters also include many stellar spectroscopic and evolutionary parameters for up to 470 million sources. These comprise Teff, log g, and [M/H] (470 million using bP/RP, 6 million using RVs), radius (470 million), mass (140 million), age (120 million), chemical abundances (up to 5 million), diffuse interstellar band analysis (0.5 million), activity indices (2 million), Hα equivalent widths (200 million), and further classification of spectral types (220 million) and emission-line stars (50 thousand). This paper is part of a series of three papers: this Paper I focusses on describing the global content of the parameters in Gaia DR3. The accompanying papers II and III focus on the validation and use of the stellar and non-stellar products, respectively. This catalogue is the most extensive homogeneous database of astrophysical parameters to date, and it is based uniquely on Gaia data. It will only be superseded in Gaia Data Release 4. This catalogue will therefore remain a key reference over the next four years, providing astrophysical parameters independ

Context. The third Gaia data release (Gaia DR3) contains, beyond the astrometry and photometry, dispersed light for hundreds of millions of sources from the Gaia prism spectra (bP and RP) and the spectrograph (RVs). This data release opens a new window on the chemo-dynamical properties of stars in our Galaxy, essential knowledge for understanding the structure, formation, and evolution of the Milky Way. Aims. To provide insight into the physical properties of Milky Way stars, we used these data to produce a uniformly-derived, all-sky catalog of stellar astrophysical parameters (APs): atmospheric properties (Teff, log g, [M/H], [α/Fe], activity index, emission lines, rotation), 13 chemical abundance estimates, evolution characteristics (radius, age, mass, bolometric luminosity), distance, and dust extinction. Methods. We developed the astrophysical parameters inference system (Apsis) pipeline to infer APs of Gaia ob.e.ts by analyzing their astrometry, photometry, bP/RP, and RVs spectra. We validate our results against other works in the literature, including benchmark stars, interferometry, and asteroseismology. Here we assessed the stellar analysis performance from Apsis statistically. Results. We describe the quantities we obtained, including the underlying assumptions and the limitations of our results. We provide guidance and identify regimes in which our parameters should and should not be used. Conclusions. Despite some limitations, this is the most extensive catalog of uniformly-inferred stellar parameters to date. These comprise Teff, log g, and [M/H] (470 million using bP/RP, 6 million using RVs), radius (470 million), mass (140 million), age (120 million), chemical abundances (5 million), diffuse interstellar band analysis (1/2 million), activity indices (2 million), Hα equivalent widths (200 million), and further classification of spectral types (220 million) and emission-line stars (50 thousand).

We present cosmological constraints from the abundance of galaxy clusters selected via the thermal sunyaev-Zel’dovich (sZ) effect in south Pole Telescope (sPT) data with a simultaneous mass calibration using weak gravitational lensing data from the Dark energy survey (Des) and the Hubb.e.space Telescope (HsT). The cluster sample is constructed from the combined sPT-sZ, sPTpol eCs, and sPTpol 500d surveys, and comprises 1,005 confirmed clusters in the redshift range 0.25–1.78 over a total sky area of 5200 deg2. We use Des Year 3 weak-lensing data for 688 clusters with redshifts z<0.95 and HsT weak-lensing data for 39 clusters with 0.6e weak-lensing measurements enab.e.robust mass measurements of sample clusters and allow us to empirically constrain the sZ ob.e.vab.e.mass relation without having to make strong assumptions about, e.g., the hydrodynamical state of the clusters. For a flat ΛCDM cosmology, and marginalizing over the sum of massive neutrinos, we measure Ωm=0.286±0.032, σ8=0.817±0.026, and the parameter combination σ8(Ωm/0.3)0.25=0.805±0.016. Our measurement of s8≡σ8Ωm/0.3=0.795±0.029 and the constraint from Planck CMb anisotropies (2018 TT, Te, ee+lowe) differ by 1.1σ. In combination with that Planck dataset, we place a 95% upper limit on the sum of neutrino masses ∑mν<0.18 eV. When additionally allowing the dark energy equation of state parameter w to vary, we obtain w=−1.45±0.31 from our cluster-based analysis. In combination with Planck data, we measure w=−1.34−0.15+0.22, or a 2.2σ difference with a cosmological constant. We use the cluster abundance to measure σ8 in five redshift bins between 0.25 and 1.8, and we find the results to be consistent with structure growth as predicted by the ΛCDM model fit to Planck primary CMb data.

A search for the standard model (sM) Higgs boson (H) produced with transverse momentum (pT) greater than 450 GeV and decaying to a charm quark-antiquark (cc¯) pair is presented. The search is performed using proton-proton collision data collected at s=13 TeV by the CMs experiment at the LHC, corresponding to an integrated luminosity of 138 fb−1. boosted H→cc¯ decay products are reconstructed as a single large-radius jet and identified using a deep neural network charm tagging technique. The method is validated by measuring the Z→cc¯ decay process, which is ob.e.ved in association with jets at high pT for the first time with a signal strength of 1.00−0.14+0.17(syst)±0.08(theo)±0.06(stat), defined as the ratio of the ob.e.ved process rate to the sM expectation. The ob.e.ved (expected) upper limit on σ(H)b(H→cc¯) is set at 47 (39) times the sM prediction at 95% confidence level.

Quasireal photons exchanged in relativistic heavy ion interactions are powerful probes of the gluonic structure of nuclei. The coherent J/ψ photoproduction cross section in ultraperipheral lead-lead collisions is measured as a function of photon-nucleus center-of-mass energies per nucleon (WγNPb) over a wide range of 40b<400 GeV. Results are obtained using data at the nucleon-nucleon center-of-mass energy of 5.02 TeV collected by the CMs experiment at the CeRN LHC, corresponding to an integrated luminosity of 1.52 nb−1. The cross section is ob.e.ved to rise rapidly at low WγNPb, and plateau above WγNPb≈40 GeV, up to 400 GeV, entering a new regime of small bjorken-x (≈6×10−5) gluons being probed in a heavy nucleus. The ob.e.ved energy dependence is not predicted by current quantum chromodynamic models.

The dependence of the ratio between the bs0 and b+ hadron production fractions, fs/fu, on the transverse momentum (pT) and rapidity of the b mesons is studied using the decay channels bs0→J/ψϕ and b+→J/ψK+. The analysis uses a data sample of proton-proton collisions at a center-of-mass energy of 13 TeV, collected by the CMs experiment in 2018 and corresponding to an integrated luminosity of 61.6 fb−1. The fs/fu ratio is ob.e.ved to depend on the b pT and to be consistent with becoming asymptotically constant at large pT. No rapidity dependence is ob.e.ved. The ratio of the b0 to b+ meson production fractions, fd/fu, is also measured, for the first time in proton-proton collisions, using the b0→J/ψK*0 decay channel. The result is found to be within 1 standard deviation of unity and independent of pT and rapidity, as expected from isospin invariance.

A search for the lepton-flavor violating decay of the Higgs boson and potential additional Higgs bosons with a mass in the range 110–160 GeV to an e±μ∓ pair is presented. The search is performed with a proton-proton collision dataset at a center-of-mass energy of 13 TeV collected by the CMs experiment at the LHC, corresponding to an integrated luminosity of 138 fb−1. No excess is ob.e.ved for the Higgs boson. The ob.e.ved (expected) upper limit on the e±μ∓ branching fraction for it is determined to be 4.4(4.7)×10−5 at 95% confidence level, the most stringent limit set thus far from direct searches. The largest excess of events over the expected background in the full mass range of the search is ob.e.ved at an e±μ∓ invariant mass of approximately 146 GeV with a local (global) significance of 3.8 (2.8) standard deviations.

The accurate simulation of additional interactions at the ATLAs experiment for the analysis of proton–proton collisions delivered by the Large Hadron Collider presents a significant challenge to the computing resources. During the LHC Run 2 (2015–2018), there were up to 70 inelastic interactions per bunch crossing, which need to be accounted for in Monte Carlo (MC) production. In this document, a new method to account for these additional interactions in the simulation chain is described. Instead of sampling the inelastic interactions and adding their energy deposits to a hard-scatter interaction one-by-one, the inelastic interactions are presampled, independent of the hard scatter, and stored as combined events. Consequently, for each hard-scatter interaction, only one such presampled event needs to be added as part of the simulation chain. For the Run 2 simulation chain, with an average of 35 interactions per bunch crossing, this new method provides a substantial reduction in MC production CPU needs of around 20%, while reproducing the properties of the reconstructed quantities relevant for physics analyses with good accuracy. © 2022, The Author(s).

A measurement is presented for the electroweak production of a W boson, a photon (γ), and two jets (j) in proton-proton collisions. The leptonic decay of the W boson is selected by requiring one identified electron or muon and large missing transverse momentum. The two jets are required to have large invariant dijet mass and large separation in pseudorapidity. The measurement is performed with the data collected by the CMs detector at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 138 fb−1. The cross section for the electroweak Wγjj production is 23.5−4.7+4.9 fb, whereas the total cross section for Wγjj production is 113±13 fb. Differential cross sections are also measured with the distributions unfolded to the particle level. All results are in agreement with the standard model expectations. Constraints are placed on anomalous quartic gauge couplings (aQGCs) in terms of dimension-8 effective field theory operators. These are the most stringent limits to date on the aQGCs parameters fM,2–5/Λ4 and fT,6–7/Λ4.
