Dual Implications of Quark Mass Hierarchies to Flavor Structure
Ying Zhang
To solve the mystery of flavor structure, we demonstrate two implications emerging from the hierarchical masses of quarks: one for the mass matrix itself and one for the CKM mixing…
A Factorized Mass Structure of Fermions and Its Fit
Qingfeng Cao, Ying Zhang
The structure of the mass matrix, a challenging problem in the Standard Model, is closely related to flavor phenomenology and the understanding of the Yukawa interaction. We derive…
Mass Matrix Rules and the Flat Pattern of Quarks
Ying Zhang
Seeking mass patterns is a key to decoding the unknown flavor puzzles in particle physics. Inspired by quark hierarchical masses, the mass matrix can universally be factorized into…
CP violation in the CKM mixing for degenerate quark masses
Ying Zhang
CP violation in the CKM mixing is discussed for the case of quark mass degeneracy that is approximate in the quark mass hierarchy limit. Differing from the traditional understandin…
Decoding Fermion Mass Pattern from Mass Hierarchy
Ying Zhang
Building an organized Yukawa structure of quarks and leptons is an essential mission to understand fermion mass hierarchy and flavor mixing in particle physics. Inspired by the sim…
