轻子扇区中的CP不守恒

CP nonconservation in the leptonic sector

Petre Dita

摘要:

本文用一种精确的方法对最近确定的中微子PMNS矩阵的模施加么正性,并说明如何从有限的实验信息中获得CP不守恒的信息。一个建议的一种新型的全球性的拟合表示所有的理论量的公约独立的参数:Jarlskog不变$J$和模数$|U_{αi}|$,能够解决的积极性问题的$|U_{e 3}|$。以这种方式,拟合将直接提供$J$的值,并且如果它不为零,则将证明在可用的实验数据中存在CP破坏。如果$|U_{e3}|^2<0$ M. Maltoni { \em et al},[New J. Phys.{ \bf 6}(2004)122]中所提出的理论得到了证实,这将意味着轻子物理领域的一个新物理。

英文摘要:

In this paper we use an exact method to impose unitarity on moduli of neutrino PMNS matrix recently determined, and show how one could obtain information on CP nonconservation from a limited experimental information. One suggests a novel type of global fit by expressing all theoretical quantities in terms of convention independent parameters: the Jarlskog invariant $J$ and the moduli $|U_{αi}|$, able to resolve the positivity problem of $|U_{e 3}|$. In this way the fit will directly provide a value for $J$, and if it is different from zero it will prove the existence of CP violation in the available experimental data. If the best fit result, $|U_{e3}|^2<0$, from M. Maltoni {\em et al}, [New J.Phys. {\bf 6} (2004) 122] is confirmed, it will imply a new physics in the leptonic sector.
