Abstract	The associated production of a Higgs boson with a W or Z boson decaying to leptons and where the Higgs boson decays to a bb ̄ pair is measured in the high transverse momentum regime, above 250 GeV, with the ATLAS detector. The analysed data, corresponding to an integrated luminosity of 139 fb−1, were collected in proton-proton collisions at the Large Hadron Collider between 2015 and 2018 at a centre-of-mass energy of √s = 13 TeV. The measured signal strength, defined as the ratio of the measured signal yield to that predicted by the Standard Model, is 0.72+0.39−0.36 corresponding to an observed (expected) significance of 2.1 (2.7) standard deviations. Fiducial cross-sections are measured in two ranges of gauge boson transverse momentum, 250– 400 GeV and above 400 GeV, according to region definitions of the simplified template cross-section framework.
