Gravitational baryogenesis models comparison in f(R) Gravity

A. S. Agrawal, S. K. Tripathy, B. Mishra

摘要:

本文研究了在各向异性Bianchi I时空中f(R)引力理论中的引力重子生成问题。物质场被认为是理想流体的物质场。提出了两种与Ricci标量的特殊形式有关的模型。在各向异性背景下,利用Ricci标量的某些特殊形式导出了重子熵比。考察了引力重子生成现象,研究了它的行为。

英文摘要:

We have studied the gravitational baryogenesis in f(R) theory of gravity with an anisotropic Bianchi I space-time. The matter field is considered to be that of perfect fluid. Two models pertaining to specific form of Ricci scalar have been presented. The baryon-to-entropy ratio has been derived with the some specific form of Ricci scalar in the anisotropic background. The gravitational baryogenesis is examined and its behaviors are studied.
