Gravitational baryogenesis in extended teleparallel theories of gravity

The article communicates gravitational baryogenesis in non-minimal f(T) gravity and f(T, B) teleparallel gravity where T denote the torsion scalar and B a boundary term. These extended teleparallel theories of gravity differ from the usual f(T) gravity and therefore could provide key insights in expounding the baryon asymmetry of the universe. Furthermore, such a study also put constraints on the model parameters of these extended teleparallel theory of gravity. I present different baryogenesis interactions proportional to partial derivative T-i, partial derivative(i)f(T), partial derivative(i)(T + B) and partial derivative(i)f(T + B) and find that both of these teleparallel theories of gravity yield viable estimates of the baron-to-entropy ratio compatible with observations except for the baryogenesis interaction proportional to partial derivative(i)(T + B). It is therefore encouraging to exercise these extended theories of gravity in other cosmological areas to under their efficiency and applicability in characterizing the current state of the universe.
