The latter is a mechanism for generating the baryon asymmetry in the universe, and relies on the coupling between the Ricci scalar curvature R and the baryon current. Gravity Lagrangians of the form L(R) ∼ Rn, where n differs from 1 (the case of the General Rela tivity) only for tiny deviations of a few percent, are consistent with the current bounds on the observed baryon asymmetry.enDr. Rabia SaleemMATHEMATICSGravityThesis
