Search for heavy resonances decaying to a W or Z boson and a Higgs boson in the qq¯ (′) bb¯ final state in pp collisions at √s = 13 TeV with the ATLAS detector

A search for heavy resonances decaying to a W or Z boson and a Higgs boson in the qq¯ (′) bb¯ final state is described. The search uses 36.1 fb −1 of proton–proton collision data at s=13 TeV collected by the ATLAS detector at the CERN Large Hadron Collider in 2015 and 2016. The data are in agreement...
