    Baryogenesis in f(R) Theory of Gravity
    (Library Information Services, COMSATS University Islamabad, Lahore Campus, 2025) Laiba Zulfiqar (FA20-BSM-018) : Adeeba Iqbal (FA20-BSM-063); Dr. Rabia Saleem; LHR TP 9926
    f (R) Theory of gravity are reviewed in the context of the so called gravitational baryoge nesis. 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.
