Search for the Higgs boson decay to a Z boson and a photon in pp collisions at s = 13 TeV and 13.6 TeV with the ATLAS detector

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

A search for the Higgs boson decay to a $Z$ boson and a photon in the $\ell\ellγ$ ($\ell = e, μ$) final state is performed using $pp$ collisions at $\sqrt{s}=13.6$ TeV recorded with the ATLAS detector at the Large Hadron Collider during …

Transforming jet flavour tagging at ATLAS

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

Jet flavour tagging enables the identification of jets originating from heavy-flavour quarks in proton-proton collisions at the Large Hadron Collider, playing a critical role in its physics programmes. This paper presents GN2, a transformer-based flavour tagging algorithm deployed by the ATLAS Collaboration …

Missing-mass search in forward-proton-tagged dilepton events with the ATLAS detector

Georges Aad, Erlend Aakvaag, B M. Acharya, Mariano Apicella et autres

A search is conducted in proton-proton collisions at the Large Hadron Collider for photon-induced production $pp\rightarrow pp+ γγ, (γγ\rightarrow VX)$ of a visible particle $V$ decaying into a pair of same-flavour charged leptons ($e^+e^-$ or $μ^+μ^-$) and an undetected invisible component $X$. …

Estimation of backgrounds from jets misidentified as $$\tau $$-leptons using the Universal Fake Factor method with the ATLAS detector

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

Abstract Processes with $$\tau $$ τ -leptons in the final state are important for Standard Model measurements and searches for physics beyond the Standard Model. The ATLAS experiment at the Large Hadron Collider observes $$\tau $$ τ -leptons produced in proton–proton collisions …
