Precision calibration of calorimeter signals in the ATLAS experiment using an uncertainty-aware neural network

A.T.L.A.S. Collaboration, G. Aad, E. Aakvaag, B.K. Abbott et autres

The ATLAS experiment at the Large Hadron Collider explores the use of modern neural networks for a multi-dimensional calibration of its calorimeter signal defined by clusters of topologically connected cells (topo-clusters). The Bayesian neural network (BNN) approach not only yields a continuous …

Search for electroweak production of supersymmetric particles in final states with two τ-leptons in $ \sqrt{s} $ = 13 TeV pp collisions with the ATLAS detector

Georges Aad, Braden Keim Abbott, Claire Adam Bourdarios, Ludovica Aperio Bella et autres

Abstract Three searches for the direct production of τ-sleptons or charginos and neutralinos in final states with at least two hadronically decaying τ-leptons are presented. For chargino and neutralino production, decays via intermediate τ-sleptons or W and h bosons are considered. The …

Search for flavour-changing neutral tqH interactions with H → γγ in pp collisions at $$ \sqrt{s} $$ = 13 TeV using the ATLAS detector

G. Aad, B. Abbott, Kira Abeling, Nils Julius Abicht et autres

Abstract A search for flavour-changing neutral interactions involving the top quark, the Higgs boson and an up-type quark q (q = c, u) is presented. The proton-proton collision data set used, with an integrated luminosity of 139 fb−1, was collected at $$ …

Observation of the $\gamma\gamma\to\tau\tau$ process in Pb+Pb collisions and constraints on the $\tau$-lepton anomalous magnetic moment with the ATLAS detector

G. Aad, B. Abbott, D. C. Abbott, K. Abeling et autres

This Letter reports the observation of $τ$-lepton-pair production in ultraperipheral lead-lead collisions Pb+Pb→Pb($γγ→ττ$)Pb and constraints on the $τ$-lepton anomalous magnetic moment $a_τ$. The dataset corresponds to an integrated luminosity of 1.44 nb$^{-1}$ of LHC Pb+Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV recorded …

Measurement of the $CP$ properties of Higgs boson interactions with $\tau$-leptons with the ATLAS detector

Georges Aad, Braden Keim Abbott, D. C. Abbott, K. Abeling et autres

A study of the charge conjugation and parity ($CP$) properties of the interaction between the Higgs boson and $\tau$-leptons is presented. The study is based on a measurement of $CP$-sensitive angular observables defined by the visible decay products of $\tau$-lepton decays, where …

Elective Cancer Surgery in COVID-19–Free Surgical Pathways During the SARS-CoV-2 Pandemic: An International, Multicenter, Comparative Cohort Study

James Glasbey, Dmitri Nepogodiev, Joana Simões, Omar M. Omar et autres

PURPOSE As cancer surgery restarts after the first COVID-19 wave, health care providers urgently require data to determine where elective surgery is best performed. This study aimed to determine whether COVID-19–free surgical pathways were associated with lower postoperative pulmonary complication rates compared …
