A search is presented for new resonances decaying to a W or Z boson and a Higgs boson in the ι+ι−bb‾, ιvbb‾ and vv‾bb‾ channels in pp collisions at √s=13TeV with the ATLAS detector at the Large Hadron Collider using a total integrated luminosity of 3.2 fb−1. The search is conducted by looking for a localized excess in the WH/ZH invariant or transverse mass distribution. No significant excess is observed, and the results are interpreted in terms of constraints on a simplified model based on a phenomenological Lagrangian of heavy vector triplets.
