Current state-of-the art calculations for inclusive slepton pair production at hadron colliders has focused on higher-order logarithms in the leading power of the threshold variable. Here, we evaluate the next-to-leading power contribution in the threshold variable to leading logarithmic accuracy. We find that the next-to-leading power contributions can be significant compared to the next-to-leading logarithmic terms at leading power, and that existing calculations underestimate the scale error for large slepton masses.

We first extend the conjecture to set-ups where moduli are present and we demand that a particle, produced during the decay of an extremal black hole via the Schwinger effect, is repelled close to the horizon of the black hole. We interpret this condition as the universal criterion imposed by the WGC for any background. Interestingly, the constraint imposed by the WGC on the particle spectrum, before the stabilization of the moduli, is independent of the background, resulting in the same bound both in Minkowski and in AdS space. For the case of AdS space, after the stabilization of the moduli, the WGC in AdS space is reproduced due to the formation of a non-singular horizon of the extremal black hole. In that case, the particle spectrum must satisfy the stronger of the two WGC conditions obtained before and after moduli stabilization. Finally, we use these results to argue that a similar version of the tower WGC should also apply to an AdS background.</p>","PeriodicalId":635,"journal":{"name":"Journal of High Energy Physics","volume":"2026 4","pages":""},"PeriodicalIF":5.5,"publicationDate":"2026-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/JHEP04(2026)208.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147796718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
