Search for New Phenomena in Final States with Two Leptons and One or No b-Tagged Jets at s=13 TeV Using the ATLAS Detector
Aad, G; Abbott, B; Abbott, DC; Abud, AA; Abeling, K; Abhayasinghe, DK; Abidi, SH; Abramowicz, H; Abreu, H; Abulaiti, Y (American Physical Society, 2021-10-01)A search for new phenomena is presented in final states with two leptons and one or no b -tagged jets. The event selection requires the two leptons to have opposite charge, the same flavor (electrons or muons), and a ... -
Search for new phenomena with top-quark pairs and large missing transverse momentum using 140 fb−1 of pp collision data at s = 13 TeV with the ATLAS detector
Aad, G; Aakvaag, E; Abbott, B; Abeling, K; Abicht, NJ; Abidi, SH; Aboelela, M; Aboulhorma, A; Abramowicz, H; Abreu, H (Springer Nature, 2024-03-26)A search is conducted for new phenomena in events with a top quark pair and large missing transverse momentum, where the top quark pair is reconstructed in final states with one isolated electron or muon and multiple jets. ... -
Search for pair production of third-generation leptoquarks decaying into a bottom quark and a τ-lepton with the ATLAS detector
Aad, G; Abbott, B; Abeling, K; Abidi, SH; Aboulhorma, A; Abramowicz, H; Abreu, H; Abulaiti, Y; Hoffman, ACA; Acharya, BS -
A search for the decays of stopped long-lived particles at root s=13 TeV with the ATLAS detector
Aad, G; Abbott, B; Abbott, DC; Abed Abud, A; Abeling, K; Abhayasinghe, DK; Abidi, SH; AbouZeid, OS; Abraham, NL; Abramowicz, H (Springer, 2021-07-23)A search for long-lived particles, which have come to rest within the ATLAS detector, is presented. The subsequent decays of these particles can produce high-momentum jets, resulting in large out-of-time energy deposits ... -
Studies of new Higgs boson interactions through nonresonant HH production in the bb¯γγ final state in pp collisions at s = 13 TeV with the ATLAS detector
Aad, G; Abbott, B; Abeling, K; Abicht, NJ; Abidi, SH; Aboulhorma, A; Abramowicz, H; Abreu, H; Abulaiti, Y; Acharya, BS -
Test of CP-invariance of the Higgs boson in vector-boson fusion production and in its decay into four leptons
Aad, G; Abbott, B; Abeling, K; Abicht, NJ; Abidi, SH; Aboulhorma, A; Abramowicz, H; Abreu, H; Abulaiti, Y; Abusleme Hoffman, AC (Springer Nature, 2024-05-09)A search for CP violation in the decay kinematics and vector-boson fusion production of the Higgs boson is performed in the H → ZZ* → 4ℓ (ℓ = e, μ) decay channel. The results are based on proton-proton collision data ... -
Tools for estimating fake/non-prompt lepton backgrounds with the ATLAS detector at the LHC
Aad, G; Abbott, B; Abbott, DC; Abeling, K; Abidi, SH; Aboulhorma, A; Abramowicz, H; Abreu, H; Abulaiti, Y; Hoffman, ACA (IOP Publishing, 2023-11-01) -
Two-particle azimuthal correlations in photonuclear ultraperipheral Pb plus Pb collisions at 5.02 TeV with ATLAS
Aad, G; Abbott, B; Abbott, DC; Abud, AA; Abeling, K; Abhayasinghe, DK; Abidi, SH; AbouZeid, OS; Abraham, NL; Abramowicz, H (American Physical Society, 2021-07-12)Two-particle long-range azimuthal correlations are measured in photonuclear collisions using 1.7 nb − 1 of 5.02 TeV Pb + Pb collision data collected by the ATLAS experiment at the CERN Large Hadron Collider. ...
