Leptoquark option for B-meson anomalies and leptonic signatures

초록

We entertain the option of scalar leptoquarks to explain the anomalies in the semileptonic decays of B mesons and the discrepancies in the lepton (g -2)(l)'s including the recent results at Fermilab E989. The Re(K(*) )and R-D(*) anomalies can be accommodated by the specific couplings for triplet and singlet leptoquarks, respectively, subject to the bounds from B -> K nu(nu) over bar. We discuss the correlation between the leptonic signatures from leptoquarks such as mu -> e gamma and the electric dipole moment of the electron and show that desirable neutrino masses can be generated dominantly by top-quark loops in the extension of the model with several doublet leptoquarks.
