B decays in an asymmetric left-right model

Motivated by recently observed disagreements with the standard model predictions in B decays, we study b{yields}d, s transitions in an asymmetric class of SU(2){sub L}xSU(2){sub R}xU(1){sub B-L} models, with a simple one-parameter structure of the right-handed mixing matrix for the quarks, which obeys the constraints from kaon physics. We use experimental constraints on the branching ratios of b{yields}s{gamma}, b{yields}ce{nu}{sub e}, and B{sub d,s}{sup 0}-B{sub d,s}{sup 0} mixing to restrict the parameters of the model: g{sub R}/g{sub L}, M{sub W{sub 2}}, M{sub H}{sup {+-}}, tan{beta} as well as the elements of the right-handed quark mixing matrix V{sub CKM}{sup R}. We present a comparison with the more commonly used (manifest) left-right symmetric model. Our analysis exposes the parameters most sensitive to b transitions and reveals a large parameter space where left- and right-handed quarks mix differently, opening the possibility of observing marked differences in behavior between the standard model and the left-right model.
