物质中中微子振荡的Toshev关系的单圈辐射修正

One-loop radiative correction to the Toshev relation for neutrino oscillations in matter

Zhi-zhong Xing, Jun-yu Zhu

摘要:

介质中相干前向中微子散射的单圈电弱辐射修正稍微违反了与物质中中微子振荡有关的三种中微子味对物质势的中性流贡献的树级普适性。我们通过推导这些有效的中微子振荡量与物质的电子数密度的微分方程来考察这种微小但非平凡的量子效应。树级Toshev关系$\sin 2\tildeθ_{23} \sin\tildeδ = \sin 2θ_{23} \sinδ$,它将基本的味道混合参数和CP破坏参数联系起来

英文摘要:

The one-loop electroweak radiative corrections to coherent forward neutrino scattering in a medium slightly violates the tree-level universality of neutral-current contributions of three neutrino flavors to the matter potential that is relevant to neutrino oscillations in matter. We examine this small but nontrivial quantum effect by deriving the differential equations of those effective neutrino oscillation quantities with respect to the electron number density of matter. The tree-level Toshev relation $\sin 2\tildeθ_{23} \sin\tildeδ = \sin 2θ_{23} \sinδ$, which links the fundamental flavor-mixing and CP-violating parameters
