General Physics 2020-04-02 v2

Abstract

The article communicates exploration of gravitational baryogenesis in presence of f(Q,T)f(Q,\mathcal{ T}) gravity where QQ denote the nonmetricity and T\mathcal{ T} the trace of the energy momentum tensor. We study various baryogenesis interactions proportional to Q˙\dot{Q} and Q˙fQ\dot{Q}f_{Q} for the f(Q,T)f(Q,\mathcal{ T}) gravity model f(Q,T)=αQn+1+βTf(Q,\mathcal{ T})=\alpha Q ^{n+1} + \beta \mathcal{ T}, where α\alpha, β\beta and nn are model parameters. Additionally we report the viable parameter spaces for which an observationally consistent baryon-to-entropy can be generated. Our results indicate that f(Q,T)f(Q,\mathcal{ T}) gravity can contribute significantly and consistently to the phenomenon of gravitational baryognesis.
