Baryogenesis in $f(Q,\mathcal{T})$ Gravity

The article communicates exploration of gravitational baryogenesis in presence of $f(Q,\mathcal{ T})$ gravity where $Q$ denote the nonmetricity and $\mathcal{ T}$ the trace of the energy momentum tensor. We study various baryogenesis interactions proportional to $\dot{Q}$ and $\dot{Q}f_{Q}$ for the $f(Q,\mathcal{ T})$ gravity model $f(Q,\mathcal{ T})=αQ ^{n+1} + β\mathcal{ T}$, where $α$, $β$ and $n$ 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 $f(Q,\mathcal{ T})$ gravity can contribute significantly and consistently to the phenomenon of gravitational baryognesis.
