A T^2-dependent coupling between the derivative of T_mu nu T^mu nu and the baryon current can generate the observed baryon asymmetry in GR and f(R,T^2) gravity, at the cost of fitted parameters.

abstract
This paper aims to recreate the gravitational baryogenesis epoch in the framework of the $f(R,L_m)$ theory of gravity, where $R$ and $L_m$ are the curvature scalar and the matter Langragian, respectively. In particular, we examine the model, $f(R,L_m) = \frac{R}{2} + L_m ^{\alpha} + \zeta$, under the supposition that the universe is saturated with dark energy and perfect fluid, with a non-zero baryon to entropy ratio during a radiation dominance era. We confine the model with the gravitational baryogenesis scenario, emphasizing the appropriate values of model parameters compatible with the baryon-to-entropy ratio observation data. Our study found that $f(R,L_m)$ gravity can considerably and steadily make a contribution to the phenomenon of gravitational baryogenesis.

Baryon asymmetry from higher-order matter contributions in gravity
A T^2-dependent coupling between the derivative of T_mu nu T^mu nu and the baryon current can generate the observed baryon asymmetry in GR and f(R,T^2) gravity, at the cost of fitted parameters.
