Search for new resonances decaying to a \(W\) or \(Z\) boson and a Higgs boson in the \(\ell^+ \ell^- b\bar b\), \(\ell \nu b\bar b\), and \(\nu\bar{\nu} b\bar b\) channels with \(pp\) collisions at \(\sqrt s = 13\) TeV with the ATLAS detector

Abstract

A search is presented for new resonances decaying to a \(W\) or \(Z\) boson and a Higgs boson in the \(\ell^+ \ell^- b\bar b\), \(\ell\nu b\bar b\), and \(\nu\bar{\nu} b\bar b\) channels in \(pp\) collisions at \(\sqrt s = 13\) TeV 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.
