对SU(5)规范耦合统一的引力修正

Gravitational correction to SU(5) gauge coupling unification

Jitesh R. Bhatt, Sudhanwa Patra, Utpal Sarkar

摘要:

对阿贝尔和非阿贝尔规范理论的规范耦合常数的引力修正是二次发散的。由于这一结果将产生有趣的后果,因此几位作者从不同的方法进行了分析。我们建议从现象学的方法来讨论这个问题。本文分析了SU(5)规范耦合统一问题,指出当包含高维不可重整化项时,引力对规范耦合常数的修正可能不为零。

英文摘要:

The gravitational corrections to the gauge coupling constants of abelian and non-abelian gauge theories has been shown to diverge quadratically. Since this result will have interesting consequences, this has been analyzed by several authors from different approaches. We propose to discuss this issue from a phenomenological approach. We analyze the SU(5) gauge coupling unification and argue that the gravitational corrections to gauge coupling constants may not vanish when higher dimensional non-renormalizable terms are included in the problem.
