Measurement of the cross section of high transverse momentum Z -> b(b)over-bar production in proton-proton collisions at root s=8 TeV with the ATLAS detector

Abstract:

This Letter reports the observation of a high transverse momentum Z→bb signal in proton-proton col-lisions at √s=8TeVand the measurement of its production cross section. The data analysed were collected in 2012 with the ATLAS detector at the LHC and correspond to an integrated luminosity of 19.5fb-1. The Z→bb decay is reconstructed from a pair of b-tagged jets, clustered with the anti-kt jet algorithm with R =0.4, that have low angular separation and form a dijet with pT > 200GeV. The sign...
