Abstract

We suggest to isolate the loop-induced gluon-initiated component ( $g g \to Z H$ ) for associated $Z H$ production by using the similarity of the Drell-Yan-like component for $Z H$ production to the $W H$ process. We argue that the cross-section ratio of the latter two processes can be predicted with high theoretical accuracy. Comparing it to the experimental $Z H / W H$ cross-section ratio should allow to probe for New Physics in the $g g \to Z H$ component at the HL-LHC. We consider typical BSM scenarios in order to exemplify the effect they would have on the proposed observable.
