"Unified framework for B-anomalies, muon g-2, and neutrino masses"


Anil Thapa , University of Virginia - Department of Physics
[Host: Julian Heeck]
ABSTRACT:

A model of radiative neutrino masses which also resolves anomalies reported in B-meson decays, RD(★) and RK(★), as well as in muon g −2 measurement, ∆aµ is presented. Neutrino masses arise in the model through loop diagrams involving TeV-scale leptoquark (LQ) scalars R2 and S3. Fits to neutrino oscillation parameters are obtained satisfying all flavorconstraints which also explain the anomalies in RD(★), RK(★) and ∆aµ within 1 σ. An isospin-3/2 Higgs quadruplet plays a crucial role in generating neutrino masses; we point out that the doubly-charged scalar contained therein can be produced in the decays of the S3 LQ, which enhances its reach to 1.1 (6.2) TeV at √s = 14 TeV high-luminosity LHC (√s = 100 TeV FCC-hh).
