Description
We search for a heavy resonance decaying into diphoton in association with at least one b jet. The search uses Run II proton-proton collision data with an integrated luminosity of 139~fb^{−1} recorded by the ATLAS experiment at a centre-of-mass energy of \sqrt{s} = 13~TeV during 2015 to 2018 at the Large Hadron Collider. Three models are tested in this final state. A Higgs boson like heavy scalar X produced with top quarks, b quarks or Z boson decaying into b\bar{b} are examined. In this Analysis, we setup limits on production cross-section times branching ratio on these models for the resonance mass ranging from 180~GeV–1.5~TeV.
