Describing relativistic fermions with two-component field
YU-Qi Chen
With a non-unitary transformation, the Lagrangian of a Dirac fermion is decomposed into two decoupled sectors. We propose to describe massive relativistic fermions in gauge theorie…

Solving the rho - pi puzzle by higher charmonium Fock states
Yu-Qi Chen
A new explanation for the longstanding puzzle of the tiny branching fraction of psi' --> rho pi relative to that for J/psi --> rho pi was proposed. In the case of J/psi, we argue t…
