Lepton flavor of four-fermion operator and fermion portal dark matter

Yuxuan He, Gang Li, Jia Liu +2

We study the ultraviolet realization of semileptonic four-fermion operator $O_{ledq}^{\hat{I}\pm {\hat{I}}^{2}11}$ that incorporates Majorana dark matter (DM) in both lepton-flavor-conserving (LFC) an…
