Searches for exclusive Higgs boson decays into D*γ and Z boson decays into D0γ and K0sγ in pp collisions at √s=13 TeV with the ATLAS detector

ATLAS Collaboration

Abstract

Searches for exclusive decays of the Higgs boson into D?? and of the Z boson into D0? and Ks 0? can probe flavour-violating Higgs boson and Z boson couplings to light quarks. Searches for these decays are performed with a pp collision data sample corresponding to an integrated luminosity of 136.3 fb?1 collected at s=13TeV between 2016–2018 with the ATLAS detector at the CERN Large Hadron Collider. In the D?? and D0? channels, the observed (expected) 95% confidence-level upper limits on the respective branching fractions are B(H?D??)<1.0(1.2)×10?3, B(Z?D0?)<4.0(3.4)×10?6, while the corresponding results in the Ks 0? channel are B(Z?Ks 0?)<3.1(3.0)×10?6. © 2024 The Author(s)
