This Letter reports the observation of a high transverse momentum Z→bb¯ signal in proton–proton collisions at s=8 TeV and 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 19.5 fb−1. The Z→bb¯ decay is reconstructed from a pair of b-tagged jets, clustered with the anti-kt jet algorithm...
