Measurement of the jet mass in high transverse momentum Z(→bb‾)γ production at √s=13TeV using the ATLAS detector

Popis výsledku v původním jazyce

The integrated fiducial cross-section and unfolded differential jet mass spectrum of high transverse momentum Z→bb‾ decays are measured in Zγ events in proton–proton collisions at s=13TeV . The data analysed were collected between 2015 and 2016 with the ATLAS detector at the Large Hadron Collider and correspond to an integrated luminosity of 36.1fb−1 . Photons are required to have a transverse momentum pT>175GeV . The Z→bb‾ decay is reconstructed using a jet with pT>200GeV , found with the anti- kt R=1.0 jet algorithm, and groomed to remove soft and wide-angle radiation and to mitigate contributions from the underlying event and additional proton–proton collisions. Two different but related measurements are performed using two jet grooming definitions for reconstructing the Z→bb‾ decay: trimming and soft drop. These algorithms differ in their experimental and phenomenological implications regarding jet mass reconstruction and theoretical precision.n
