费米子混合的非局域理论

A nonlocal theory of fermion mixing

Antonio Capolupo, Aniello Quaranta, Raoul Serao

AI总结:

本文提出费米子混合的非局域理论,仅非局域化混合项并用路径积分计算跃迁概率,所得振荡公式在适当极限下回到局域结果,并分析了弦启发核带来的现象学偏差。

摘要:

我们研究了两味费米子混合的非局域推广,并通过路径积分形式计算跃迁概率。在我们的处理中,仅对混合项进行非局域化,并考虑小混合角下的微扰相互作用。所推导的振荡公式在取适当极限时约化为正确的局域形式。我们将该形式应用于若干弦启发的非局域化核,并讨论了与局域理论的现象学偏差。

英文摘要:

We study a nonlocal generalization of two flavor fermion mixing and compute the transition probability by means of the path integral formalism. In our treatment, we delocalize only the mixing term, and consider a perturbative interaction with a small mixing angle. The oscillation formula derived reduces to the correct local form when the appropriate limit is considered. We apply our formalism to some string-inspired delocalization kernels and discuss the phenomenological deviations from the local theory.
