Discrepancies in simultaneous explanation of flavor anomalies and IceCube PeV events using leptoquarks

Abstract

Leptoquarks have been suggested to solve a variety of discrepancies between the expected and observed phenomenon. In this paper, we show that the scalar doublet leptoquark with hypercharge $7/6$ can simultaneously explain the recent measurement of ${R}_{K}$, ${R}_{{K}^{*}}$, the excess in anomalous magnetic moment of muon, and the observed excess in IceCube high energy starting events data. For an appropriate choice of couplings, the flavor anomalies are generated at one-loop level and IceCube data is explained via resonant production of the leptoquark. Several constraints from LHC searches are imposed on the model parameter space.
