论文摘要
近年来观察到的,矢量leptoquarks可以解决与$ b \ to c \ ellν$和$ b \ to s \ ell \ ell \ ell $ transitions the of $ b \ to C \ ell n $ transitions的衰减中的Lepton风味普遍性异常。通常,这些leptoquark会产生新的CP违规来源。在本文中,我们探讨了在Leptonic和Hadronic Systems中电力偶极矩(EDM)的限制和发现潜力。我们为一个循环的载体leptoquark诱导的偶极矩提供了最通用的表达。我们发现,tau的$ O(1)$ CP抗侵入阶段可以导致相应的EDM在下一代EDM实验的范围内,并且电子EDM上的现有界限已经对CP-Violation Electon耦合构成了严格的限制。
Vector leptoquarks can address the lepton flavor universality anomalies in decays associated with the $b \to c \ell ν$ and $b \to s \ell \ell$ transitions, as observed in recent years. Generically, these leptoquarks yield new sources of CP violation. In this paper, we explore constraints and discovery potential for electric dipole moments (EDMs) in leptonic and hadronic systems. We provide the most generic expressions for dipole moments induced by vector leptoquarks at one loop. We find that $O(1)$ CP-violating phases in tau and muon couplings can lead to corresponding EDMs within reach of next-generation EDM experiments, and that existing bounds on the electron EDM already put stringent constraints on CP-violating electron couplings.
