Claims

C1strongest claim

the present F(R,Sigma,T) gravity framework with particle creation provides a viable geometrical description of the late-time accelerated Universe and remains compatible with recent cosmological observations.

C2weakest assumption

The specific functional form chosen for F(R,Sigma,T) together with the chosen particle-creation rate and variable Chaplygin-gas parametrization can simultaneously satisfy the Friedmann equations, fit the data, and produce monotonically increasing entropy at the apparent horizon.

C3one line summary

A model in F(R, Sigma, T) gravity with gravitationally induced particle creation and variable generalized Chaplygin gas fits Pantheon+ and Hubble data and shows consistent entropy evolution at the apparent horizon.
