Search for a new pseudoscalar decaying into a pair of bottom and antibottom quarks in top-associated production in =13 TeV proton-proton collisions with the ATLAS detector
ATLAS Collaboration
A search for a pseudoscalar produced in association with a top-quark pair, or in association with a single top quark plus a boson, with the pseudoscalar decaying into -q…
Search for heavy neutral leptons in decays of W bosons using leptonic and semi-leptonic displaced vertices in TeV collisions with the ATLAS detector
ATLAS Collaboration
A search is performed for long-lived heavy neutral leptons (HNLs), produced through the decay of a boson along with a muon or electron. Two channels are explored: a leptonic ch…
Estimation of backgrounds from jets misidentified as -leptons using the Universal Fake Factor method with the ATLAS detector
ATLAS Collaboration
Processes with -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 Ha…
Search for Higgs boson decays into a pair of pseudoscalar particles in the final state using collisions at TeV with the ATLAS detector
ATLAS Collaboration
A search for exotic decays of the 125 GeV Higgs boson into a pair of new spin-0 particles, , where one decays into a photon pair and the other into a -lepton pair, is…
Test of lepton flavour universality in -boson decays into electrons and -leptons using collisions at TeV with the ATLAS detector
ATLAS Collaboration
A measurement of the ratio of the branching fractions, , is performed using a sample of bosons originating from top-quark decays to final s…
Precision calibration of calorimeter signals in the ATLAS experiment using an uncertainty-aware neural network
ATLAS Collaboration
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 to…
