New rephasing invariants and CP violation built from the trios of the CKM or PMNS matrix elements

Shu Luo, Zhi-zhong Xing

Given the $3\times 3$ Cabibbo-Kobayashi-Maskawa (CKM) quark flavor mixing matrix $V$, we define a new set of rephasing invariants in terms of the "trios" of its nine elements: $\lo…
