Electroweak, QCD and flavour physics studies with ATLAS data from Run 2 of the LHC

G. Aad, Erlend Aakvaag, B. Abbott, Sara Abdelhameed et autres

A summary of precision measurements sensitive to electroweak, QCD and quark-flavour effects performed by the ATLAS Collaboration at the Large Hadron Collider is reported. The measurements are predominantly performed on proton-proton ($pp$) collision data recorded at a centre-of-mass energy of 13 TeV …

Measurement of $W^{\pm}$-boson differential cross-sections in proton-proton collisions with low pile-up data at $\sqrt{s} = 5.02$ TeV and $13$ TeV with the ATLAS detector

Erlend Aakvaag, B. Abbott, Sara Abdelhameed, Kira Abeling et autres

High precision single-differential $W^\pm $-boson production cross-sections as a function of electron or muon transverse momentum $p_\textrm{T}$ or their pseudorapity $\eta $, as well as double-differential cross-sections as functions of these variables, are measured in proton–proton collisions at centre-of-mass energies $\sqrt{s}=5.02$ TeV …

A simplified configuration for common algorithms for ATLAS analysis

Joseph Earl Lambert, N. Krumnack, Matthew Kenneth Maroun, W. A. Leight et autres

In the ATLAS analysis model, users interact with specialized algorithms to perform a variety of tasks on their physics objects including calibration, identification, and obtaining systematic uncertainties for simulated events. These algorithms have a wide variety of configurations, and often must be …

The quest to discover supersymmetry at the ATLAS experiment

G. Aad, Erlend Aakvaag, B. Abbott, Kira Abeling et autres

The search for supersymmetry with the ATLAS experiment at the CERN Large Hadron Collider intensified after the discovery of the Higgs boson in 2012. The search programme expanded in both breadth and depth, profiting from the increased integrated luminosity and higher centre-of-mass …

Measurement of the production of a $W$ boson in association with a charmed hadron in $pp$ collisions at $\sqrt{s} = 13\,\mathrm{TeV}$ with the ATLAS detector

B. Abbott, K. Abeling, S. H. Abidi, A. Aboulhorma et autres

The production of a $W$ boson in association with a single charm quark is studied using 140 $\mathrm{fb}^{-1}$ of $\sqrt{s} = 13\,\mathrm{TeV}$ proton-proton collision data collected with the ATLAS detector at the Large Hadron Collider. The charm quark is tagged by a …

Measurement of jet substructure in boosted $t\bar{t}$ events with the ATLAS detector using 140 fb$^{-1}$ of 13 TeV $pp$ collisions

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

Measurements of the substructure of top-quark jets are presented, using 140 fb$^{-1}$ of 13 TeV $pp$ collision data recorded with the ATLAS detector at the LHC. Top-quark jets reconstructed with the anti-$k_{t}$ algorithm with a radius parameter $R=1.0$ are selected in top-quark …

arXiv : Search for exotic decays of the Higgs boson into long-lived particles in $pp$ collisions at $\sqrt{s} = 13$ TeV using displaced vertices in the ATLAS inner detector

G. Aad, A. Kupčo, J. W. O. Chan, M. A. Principe Martin et autres

A novel search for exotic decays of the Higgs boson into pairs of long-lived neutral particles, each decaying into a bottom quark pair, is performed using 139 fb$^{-1}$ of $\sqrt{s} = 13$ TeV proton-proton collision data collected with the ATLAS detector at …

Charged-lepton-flavour violation at the LHC: a search for $Z\to e\tau/\mu\tau$ decays with the ATLAS detector

G. Aad, Brad Abbott, D. C. Abbott, A. Abed Abud et autres

In the Standard Model of particle physics, leptons are key building blocks of matter and come in three families (flavours). Leptons of different flavours have the same properties, except for their mass. In addition, the number of leptons in each family is …
