摘要:

我们提出了一类新的测试,寻找轻子味非普适性(LFNU)使用比率可观的基础上潜在的LFNU新物理(NP)在几个(看似独立的)双轻子和单轻子+喷流过程的影响之间的相关性。通过研究涉及第三代夸克的LFNU 4-费米相互作用产生的效应证明了这一点。我们发现,当使用各种双轻子+喷注和单轻子+喷注过程之间的关联时,LFNU 4-Fermi算符对尺度($Λ$)的敏感性显著提高,在HL-LHC上达到了$Λ\sim {\cal O}(10)$ ~TeV。

英文摘要:

We suggest a new class of tests for searching for lepton flavor non-universality (LFNU) using ratio observables and based on correlations among the underlying LFNU new physics (NP) effects in several (seemingly independent) di-lepton and single lepton + jet(s) processes. This is demonstrated by studying the effects generated by LFNU 4-Fermi interactions involving 3rd generation quarks. We find that the sensitivity to the scale ($Λ$) of the LFNU 4-Fermi operators significantly improves when the correlations among the various di-lepton +jets and single-lepton + jets processes are used, reaching $Λ\sim {\cal O}(10)$~TeV at the HL-LHC.
