Observation of WZγ Production in pp Collisions at s= 13 TeV with the ATLAS Detector

This Letter reports the observation of W Z γ production and a measurement of its cross section using 140.1±1.2 fb− 1 of proton-proton collision data recorded at a center-of-mass energy of 13 TeV by the ATLAS detector at the Large Hadron Collider. The W Z γ production cross section, with both the W and Z bosons decaying leptonically, p p→ W Z γ→ ℓ′±ν ℓ+ ℓ− γ (ℓ (′)= e, μ), is measured in a fiducial phase-space region defined such that the leptons and the photon have high transverse momentum and the photon is isolated. The cross section is found to be 2.01±0.30 (stat)±0.16 (syst) fb. The corresponding standard model predicted cross section calculated at next-to-leading order in perturbative quantum chromodynamics and at leading order in the electroweak coupling constant is 1.50±0.06 fb. The observed significance of the W Z γ signal is 6.3 σ, compared with an expected significance of 5.0 σ.

Differential cross-section measurements of the production of four charged leptons in association with two jets using the ATLAS detector

Differential cross-sections are measured for the production of four charged leptons in association with two jets. These measurements are sensitive to final states in which the jets are produced via the strong interaction as well as to the purely-electroweak vector boson scattering process. The analysis is performed using proton-proton collision data collected by ATLAS at= 13 TeV and with an integrated luminosity of 140 fb− 1. The data are corrected for the effects of detector inefficiency and resolution and are compared to state-of-the-art Monte Carlo event generator predictions. The differential cross-sections are used to search for anomalous weak-boson self-interactions that are induced by dimension-six and dimension-eight operators in Standard Model effective field theory.

Measurement of the tt¯ cross section and its ratio to the Z production cross section using pp collisions at s= 13.6 TeV with the ATLAS detector

The inclusive top-quark-pair production cross section σ t t¯ and its ratio to the Z-boson production cross section have been measured in proton–proton collisions at s= 13.6 TeV, using 29 fb− 1 of data collected in 2022 with the ATLAS experiment at the Large Hadron Collider. Using events with an opposite-charge electron-muon pair and b-tagged jets, and assuming Standard Model decays, the top-quark-pair production cross section is measured to be σ t t¯= 850±3 (stat.)±18 (syst.)±20 (lumi.) pb. The ratio of the t t¯ and the Z-boson production cross sections is also measured, where the Z-boson contribution is determined for inclusive e+ e− and μ+ μ− events in a fiducial phase space. The relative uncertainty on the ratio is reduced compared to the t t¯ cross section, thanks to the cancellation of several systematic uncertainties. The result for the ratio, R t t¯/Z= 1.145±0.003 (stat.)±0.021 (syst.)±0.002 (lumi.) is consistent …

Search for non-resonant production of semi-visible jets using Run 2 data in ATLAS

Semi-visible jets, with a significant contribution to the event's missing transverse momentum, can arise in strongly interacting dark sectors. This results in an event topology where one of the jets can be aligned with the direction of the missing transverse momentum. The first search for semi-visible jets produced via a t-channel mediator exchange is presented. The analysis uses proton-proton collisions with an integrated luminosity of 139 fb−1 and a centre-of-mass energy of 13 TeV, collected with the ATLAS detector during the Run 2 of the LHC. No excess over Standard Model predictions is observed. Assuming a coupling strength of unity between the mediator, a Standard Model quark and a dark quark, mediator masses up to 2.7 TeV are excluded at the 95% confidence level. Upper limits on the coupling strength are also derived.

Search for pair production of squarks or gluinos decaying via sleptons or weak bosons in final states with two same-sign or three leptons with the ATLAS detector

A search for pair production of squarks or gluinos decaying via sleptons or weak bosons is reported. The search targets a final state with exactly two leptons with same-sign electric charge or at least three leptons without any charge requirement. The analysed data set corresponds to an integrated luminosity of 139 fb− 1 of proton-proton collisions collected at a centre-of-mass energy of 13 TeV with the ATLAS detector at the LHC. Multiple signal regions are defined, targeting several SUSY simplified models yielding the desired final states. A single control region is used to constrain the normalisation of the WZ+ jets background. No significant excess of events over the Standard Model expectation is observed. The results are interpreted in the context of several supersymmetric models featuring R-parity conservation or R-parity violation, yielding exclusion limits surpassing those from previous searches. In models …

Search for heavy, long-lived, charged particles with large ionisation energy loss in pp collisions at = 13 TeV using the ATLAS experiment and the full Run 2 dataset

This paper presents a search for hypothetical massive, charged, long-lived particles with the ATLAS detector at the LHC using an integrated luminosity of 139 fb− 1 of proton–proton collisions at= 13 TeV. These particles are expected to move significantly slower than the speed of light and should be identifiable by their high transverse momenta and anomalously large specific ionisation losses, dE/dx. Trajectories reconstructed solely by the inner tracking system and ad E/dx measurement in the pixel detector layers provide sensitivity to particles with lifetimes down to(1) ns with a mass, measured using the Bethe–Bloch relation, ranging from 100 GeV to 3 TeV. Interpretations for pair-production of R-hadrons, charginos and staus in scenarios of supersymmetry compatible with these particles being long-lived are presented, with mass limits extending considerably beyond those from previous searches in broad …

arXiv: Improving topological cluster reconstruction using calorimeter cell timing in ATLAS

The ATLAS experiment [1], one of the four major experiments at the LHC [2], relies on the precise measurement of particle showers as the starting point for physics object reconstruction. Calorimeter showers are reconstructed by clustering groups of topologically connected calorimeter cells, the first step in this process involving cells with high absolute energy relative to calorimeter noise [3]. The produced clusters are referred to as topo-clusters and provide the input to the reconstruction of a number of physics objects, including jets, electrons, ????-leptons and missing transverse momentum (???? miss T). The topological cell clustering algorithm is well established and performed very well during the LHC Run 1 and Run 2 data-taking periods, from 2010 to 2012 and 2015 to 2018 respectively. However, further improvement is possible, especially in view of the increased luminosity foreseen in LHC Run 3 and beyond.At the LHC, bunches of about 10 11 protons collide every 25 ns, giving rise to multiple ???????? interactions in each bunch-crossing. 1 Signals from particles produced in additional soft pp collisions pile up on top of those from the pp hard-scattering that triggered the ATLAS data-recording process. If the additional particles are produced in the same bunch-crossing that produced the recorded event’s pp hard-scattering, they are referred to as in-time pile-up, whereas if they are produced in the previous or next bunch-crossings they are called out-of-time pile-up. Calorimeter signals are sensitive to both in-time and out-of-time pile-up, which can result in the formation of additional topo-clusters, as well as spurious contributions to those originating from …

Search for heavy Higgs bosons with flavour-violating couplings in multi-lepton plus b-jets final states in pp collisions at 13 TeV with the ATLAS detector

A search for new heavy scalars with flavour-violating decays in final states with multiple leptons and -tagged jets is presented. The results are interpreted in terms of a general two-Higgs-doublet model involving an additional scalar with couplings to the top-quark and the three up-type quarks (, , and ). The targeted signals lead to final states with either a same-sign top-quark pair, three top-quarks, or four top-quarks. The search is based on a data sample of proton-proton collisions at TeV recorded with the ATLAS detector during Run 2 of the Large Hadron Collider, corresponding to an integrated luminosity of 139f b. Events are categorised depending on the multiplicity of light charged leptons (electrons or muons), total lepton charge, and a deep-neural-network-based categorisation to enhance the purity of each of the signals. Masses of an additional scalar boson between GeV with couplings , , and are excluded at 95% confidence level. Additional interpretations are provided in models of -parity violating supersymmetry, motivated by the recent flavour and anomalies.
