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.
我们建议通过利用与Drell-Yan类过程中产生的类成分的相似性，来分离关联产生中由圈诱导的胶子引发的成分（ ）。我们认为后两个过程的截面比可以用高理论精度进行预测。将其与实验截面比进行比较，应该能够在高亮度大型强子对撞机（HL-LHC）上探测 成分中的新物理。我们考虑典型的超出标准模型（BSM）情景，以举例说明它们对所提议的可观测量的影响。
