Constraint on the total width of the Higgs boson from Higgs boson and four-top-quark measurements in pp collisions at $\sqrt{s}$ = 13 TeV with the ATLAS detector

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

This Letter presents a constraint on the total width of the Higgs boson (ΓH) using a combined measurement of on-shell Higgs boson production and the production of four top quarks, which involves contributions from off-shell Higgs boson-mediated processes. This method relies on …

Measurement of jet track functions in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector

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

Measurements of jet substructure are key to probing the energy frontier at colliders, and many of them use track-based observables which take advantage of the angular precision of tracking detectors. Theoretical calculations of track-based observables require `track functions', which characterize the transverse …

Probing the Higgs boson CP properties in vector-boson fusion production in the $H\rightarrowτ^+τ^-$ channel with the ATLAS detector

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

The CP properties of the Higgs boson are studied in the vector-boson fusion production mode. The analysis exploits the decay mode of the Higgs boson into two $τ$-leptons using 140 fb$^{-1}$ of proton-proton collision data at $\sqrt{s}=13$ TeV collected by the ATLAS …

Measurement of photonuclear jet production in ultra-peripheral Pb+Pb collisions at $\sqrt{s_{\text{NN}}} = 5.02$ TeV with the ATLAS detector

B. Abbott, Sara Abdelhameed, K. Abeling, Nils Julius Abicht et autres

In ultra-relativistic heavy ion collisions at the LHC, each nucleus acts a sources of high-energy real photons that can scatter off the opposing nucleus in ultra-peripheral photonuclear ($γ+A$) collisions. Hard scattering processes initiated by the photons in such collisions provide a novel …

Beam-induced backgrounds measured in the ATLAS detector during local gas injection into the LHC beam vacuum

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

Abstract Inelastic beam-gas collisions at the Large Hadron Collider (LHC), within a few hundred metres of the ATLAS experiment, are known to give the dominant contribution to beam backgrounds. These are monitored by ATLAS with a dedicated Beam Conditions Monitor (BCM) and …
