We suggest to isolate the loop-induced gluon-initiated component (
) for associated 
production by using the similarity of the Drell–Yan-like component for production to the 
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 
cross-section ratio should allow to probe for new physics in the component at the HL-LHC. We consider typical BSM scenarios in order to exemplify the effect they would have on the proposed observable.
