Observation of centrality-dependent dijet transverse momentum imbalance in O+O and Ne+Ne collisions at $\ensuremath{\sqrt{s_{\mathrm{NN}}}} = 5.36$ TeV with the ATLAS detector

Georges Aad, Erlend Aakvaag, Braden Keim Abbott, Sara Abdelhameed et autres

The ATLAS experiment presents an observation of a centrality-dependent dijet transverse momentum imbalance in O+O and Ne+Ne collisions at a nucleon–nucleon center-of-mass energy of 5.36 TeV at the Large Hadron Collider. The measurement uses 8.0 nb$^{-1}$ of O+O and 1.0 nb$^{-1}$ of …

Probing the Higgs-top Yukawa interaction in the $t\bar{t}H$ and $tH$ processes using $H\rightarrow\gamma\gamma$ with the ATLAS detector

Georges Aad, Erlend Aakvaag, Braden Keim Abbott, Sara Abdelhameed et autres

A study of the structure of the coupling between the Higgs boson and the top quark is performed using events from $t\bar{t}H$ and $tH$ production in the $H\rightarrow\gamma\gamma$ decay channel, with 164 fb$^{-1}$ of proton-proton collision data at a center-of-mass energy of …

Search for a leptoquark in events with a hadronically decaying $\tau$-lepton and missing transverse momentum using $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector

Georges Aad, Erlend Aakvaag, Braden Keim Abbott, Sara Abdelhameed et autres

A search for leptoquark signals is performed in final states with a hadronically decaying $\tau$-lepton and missing transverse momentum, using data from proton--proton collisions at a centre-of-mass energy of $\sqrt{s}=13$ TeV recorded by the ATLAS detector at the Large Hadron Collider during …

Differential measurements of $\gamma\gamma\to\tau\tau$ and constraints on $\tau$-lepton electromagnetic moments in Pb+Pb collisions at $\sqrt{s_{_\text{NN}}} = 5.02$ TeV with ATLAS

Georges Aad, Erlend Aakvaag, Braden Keim Abbott, Sara Abdelhameed et autres

This paper presents the first differential fiducial measurements of $\gamma\gamma\to\tau\tau$ using 1.93 nb$^{-1}$ of Pb+Pb data at $\sqrt{s_{_\text{NN}}} = 5.02$ TeV recorded by the ATLAS detector. Events in which one of the $\tau$-leptons decays into a muon and two neutrinos $\tau\to\nu_\tau\bar{\nu}_\mu\mu$ are …

Study of $t\bar{t}$ threshold effects in $e\mu$ differential distributions measured in $\sqrt{s}=13$ TeV $pp$ collisions with the ATLAS detector

Georges Aad, Erlend Aakvaag, Braden Keim Abbott, Sara Abdelhameed et autres

The recent ATLAS measurement of the normalised $e\mu$ dilepton invariant mass and azimuthal angle distributions in $\sqrt{s}=13$ TeV $pp$ collisions at the Large Hadron Collider is extended to study the sensitivity to the formation of quasi-bound states near the $t\bar{t}$ threshold. The …

Search for quantum black holes in lepton+jet final states using proton-proton collisions at $\sqrt{s}=13.6$ TeV with the ATLAS detector

Georges Aad, Erlend Aakvaag, Braden Keim Abbott, Sara Abdelhameed et autres

A search for quantum black holes in electron+jet or muon+jet final states with high invariant mass is performed. The analysis uses data from $\sqrt{s}=13.6~\textrm{TeV}$ $pp$ collisions recorded by the ATLAS detector between 2022 and 2024 during Run 3 of the Large Hadron …

Measurement of jet photoproduction in ultra-peripheral Pb+Pb collisions without nuclear breakup at $\sqrt{s_\mathrm{NN}} = 5.02$ TeV with the ATLAS detector

Georges Aad, Erlend Aakvaag, B M. Acharya, Sergio Javier Arbiol Val et autres

In ultra-relativistic heavy ion collisions at the LHC, each nucleus acts as a source of high-energy quasi-real photons that can participate in scattering processes without causing either participating nucleus to break up and emit forward neutrons. This paper extends recent measurements of …

Track and Vertex Reconstruction with the ATLAS Inner Detector

Georges Aad, Erlend Aakvaag, Bobby Samir Acharya, Sergio Javier Arbiol Val et autres

Charged-particle reconstruction is a fundamental part of the event reconstruction in modern multi-purpose high-energy physics detectors. This paper describes the algorithms used to reconstruct charged particles and primary vertices with the ATLAS Inner Detector. The most recent software configuration deployed for data-taking …
