Abstract
Motivated by the work of Paliathanasis et al. (A. Paliathanasis and G. Leon, “Cosmological solutions in Hořava–Lifshitz scalar field theory,” ZnA, vol. 75, p. 523, 2020), this work reports the baryogenesis in Hořava–Lifshitz cosmology by taking the background evolution as modified Chaplygin gas and modified holographic dark energy. The Starobinsky potential has been selected to initiate the study. The scalar field and its potential have been reconstructed and found to be consistent with the universe’s expansion. The quintessence behaviour of equation of state parameters has been observed for both cases. Finally, baryogenesis has been studied in both cases. The baryon entropy ratio attained the observed value. It is also well explained that either the model will achieve an equal number of baryon and antibaryon densities or will satisfy the Generalized Second Law of Thermodynamics.
