Exploiting the WH/ZH symmetry in the search for new physics
Abstract We suggest to isolate the loop-induced gluon-initiated component ($$gg\rightarrow ZH$$ gg→ZH ) for associated $$ZH$$ ZH production by using the similarity of the Drell–Yan-like component for $$ZH$$ ZH production to the $$WH$$ WH process. We argue that the cross-section ratio of the latter t...

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