Combination of searches for heavy spin-1 resonances using 139 fb of proton-proton collision data at TeV with the ATLAS detector

A combination of searches for new heavy spin-1 resonances decaying into different pairings of , , or Higgs bosons, as well as directly into leptons or quarks, is presented. The data sample used corresponds to 139 fb of proton-proton collisions at = 13 TeV collected during 2015-2018 with the ATLAS detector at the CERN Large Hadron Collider. Analyses selecting quark pairs (, , , and ) or third-generation leptons ( and ) are included in this kind of combination for the first time. A simplified model predicting a spin-1 heavy vector-boson triplet is used. Cross-section limits are set at the 95% confidence level and are compared with predictions for the benchmark model. These limits are also expressed in terms of constraints on couplings of the heavy vector-boson triplet to quarks, leptons, and the Higgs boson. The complementarity of the various analyses increases the sensitivity to new physics, and the resulting constraints are stronger than those from any individual analysis considered. The data exclude a heavy vector-boson triplet with mass below 5.8 TeV in a weakly coupled scenario, below 4.4 TeV in a strongly coupled scenario, and up to 1.5 TeV in the case of production via vector-boson fusion.

arXiv : Search for low-mass resonances decaying into two jets and produced in association with a photon or a jet at TeV with the ATLAS detector

The Standard Model of particle physics (SM) successfully describes a wide range of phenomena across many orders of magnitude of energy at colliders, astrophysical observatories, and other experiments [1]. Nevertheless it fails to account for many observed phenomena, such as the presence of dark matter (DM)[2–4] and the imbalance of matter over antimatter in the observable universe [5]. While there are a wide range of proposed models of physics beyond the SM (BSM) to explain these effects [6–17], this paper focuses on a search for a hadronically decaying resonance

Search for invisible particles produced in association with single top quarks in proton-proton collisions at =13 TeV with the ATLAS detector

A search for the production of single-top-quarks in association with missing energy is performed in proton–proton collisions at a centre-of-mass energy of with the ATLAS experiment at the large hadron collider using data collected in 2012, corresponding to an integrated luminosity of fb. In this search, the boson from the top quark is required to decay into an electron or a muon and a neutrino. No deviation from the standard model prediction is observed, and upper limits are set on the production cross-section for resonant and non-resonant production of an invisible exotic state in association with a right-handed top quark. In the case of resonant production, for a spin- resonance with a mass of GeV, an effective coupling strength above is excluded at 95 confidence level for the top quark and an invisible spin- state with mass between and GeV. In the case of non-resonant production, an effective …

Measurement of -channel production of single top quarks and antiquarks in collisions at 13 TeV using the full ATLAS Run 2 data sample

The production of single top quarks and top antiquarks via the -channel exchange of a virtual boson is measured in proton-proton collisions at a centre-of-mass energy of 13 TeV at the LHC using of ATLAS data. The total cross-sections are determined to be and for top-quark and top-antiquark production, respectively. The combined cross-section is found to be and the cross-section ratio is . The predictions at next-to-next-to-leading-order in quantum chromodynamics are in good agreement with these measurements. The predicted value of using different sets of parton distribution functions is compared with the measured value, demonstrating the potential to further constrain the functions when using this result in global fits. The measured cross-sections are interpreted in an effective field theory approach, setting limits at the 95% confidence level on the strength of a four-quark operator and an operator coupling the third quark generation to the Higgs boson doublet: and . The constraint at the 95% confidence level is derived from the measured value of . In a more general approach, pairs of CKM matrix elements involving top quarks are simultaneously constrained, leading to confidence contours in the corresponding two-dimensional parameter spaces.

arXiv: Performance of the ATLAS forward proton Time-of-Flight detector in Run 2

A significant fraction of proton–proton (pp) collisions at the LHC proceeds via processes where one or both protons stay intact, ie pp→ pX and pp→ pXp, respectively. When an intact proton is observed in the final state, it is typically accompanied by a large rapidity gap, a region devoid of hadronic activity [1, 2] between the final system X and the leading proton (s). This topology is usually explained in terms of an absence of colour connection between the outgoing proton (s) and the final state X. Most of such processes are called diffractive and are described by Pomeron exchange [3, 4].Diffractive processes include elastic scattering (pp→ pp), central diffractive processes (CD, pp→ pXp), single diffractive dissociation (SD, pp→ pX), and double diffractive dissociation (DD, pp→ XY). The intact protons produced in SD and CD processes emerge deflected at very small angles relative to the incoming proton beam, such that they escape detection in the ATLAS inner detector and calorimeters. They can be detected and measured using dedicated proton detectors positioned far from the interaction point (IP) and close to the beam. These are known as forward proton detectors. In ATLAS [5], there are two forward proton detector systems, Absolute Luminosity for ATLAS (ALFA)[6] and ATLAS Forward Proton detector system (AFP)[7]. The scope of ALFA is to measure elastic processes and soft diffractive dissociation processes, requiring special beam optics settings, while AFP is used to collect data with forward protons during the nominal operation of the ATLAS detector to probe mainly hard-scale diffractive and photon-induced processes.

Measurement and interpretation of same-sign W boson pair production in association with two jets in pp collisions at s = 13 TeV with the ATLAS detector

This paper presents the measurement of fiducial and differential cross sections for both the inclusive and electroweak production of a same-sign W-boson pair in association with two jets (W±W±jj) using 139 fb− 1 of proton-proton collision data recorded at a centre-of-mass energy of s = 13 TeV by the ATLAS detector at the Large Hadron Collider. The analysis is performed by selecting two same-charge leptons, electron or muon, and at least two jets with large invariant mass and a large rapidity difference. The measured fiducial cross sections for electroweak and inclusive W±W±jj production are 2.92±0.22 (stat.)±0.19 (syst.) fb and 3.38±0.22 (stat.)±0.19 (syst.) fb, respectively, in agreement with Standard Model predictions. The measurements are used to constrain anomalous quartic gauge couplings by extracting 95% confidence level intervals on dimension-8 operators. A search for doubly charged Higgs bosons H±±that are produced in vector-boson fusion processes and decay into a same-sign W boson pair is performed. The largest deviation from the Standard Model occurs for an H±±mass near 450 GeV, with a global significance of 2.5 standard deviations.

Inclusive and differential cross-section measurements of production in collisions at TeV with the ATLAS detector, including EFT and spin-correlation …

Measurements of inclusive and normalized differential cross sections of the associated production of top quark-antiquark and bottom quark-antiquark pairs, ttbb, are presented. The results are based on data from proton-proton collisions collected by the CMS detector at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 138 fb− 1. The cross sections are measured in the lepton+ jets decay channel of the top quark pair, using events containing exactly one isolated electron or muon and at least five jets. Measurements are made in four fiducial phase space regions, targeting different aspects of the ttbb process. Distributions are unfolded to the particle level through maximum likelihood fits, and compared with predictions from several event generators. The inclusive cross section measurements of this process in the fiducial phase space regions are the most precise to date. In most cases, the measured inclusive cross sections exceed the predictions with the chosen generator settings. The only exception is when using a particular choice of dynamic renormalization scale, µR= 12 ni= t, t, b, b m1/4
