A theory of R(D*, D) anomaly with righthanded currents
Abstract
We present an ultraviolet complete theory for the R( D ^{*}) and R( D) anomaly in terms of a low mass W ^{±} _{ R} gauge boson of a class of leftright symmetric models. These models, which are based on the gauge symmetry SU(3) _{c} × SU(2) _{L} × SU(2) _{R} × U(1) _{B  L}, utilize vectorlike fermions to generate quark and lepton masses via a universal seesaw mechanism. A parity symmetric version as well as an asymmetric version are studied. A light sterile neutrino emerges naturally in this setup, which allows for new decay modes of Bmeson via righthanded currents. We show that these models can explain R( D ^{*}) and R( D) anomaly while being consistent with LHC and LEP data as well as low energy flavor constraints arising from \( {K}_L{K}_S,\kern0.5em {B}_{d,s}{\overline{B}}_{d,s},\kern0.5em D\overline{D} \) mixing, etc., but only for a limited range of the W _{R} mass: 1.2 (1.8) TeV ≤ \( {M}_{W_R} \) ≤ 3 TeV for parity asymmetric (symmetric) Yukawa sectors. The ratio R( D)/ R( D ^{*}) is predicted to be ≃ 1.16, which is the same as in the Standard Model. The light sterile neutrinos predicted by the model may be relevantmore »

The light sterile neutrinos predicted by the model may be relevant for explaining the MiniBoone and LSND neutrino oscillation results. The parity symmetric version of the model provides a simple solution to the strong CP problem without relying on the axion. It also predicts an isospin singlet top partner with a mass MT = (1.5  2.5) TeV.},
