Renormalization in general theories with inter-generation mixing

Understand

We derive general and explicit expressions for the unrenormalized and renormalized dressed propagators of fermions in parity-nonconserving theories with inter-generation mixing.

• The mass eigenvalues, the corresponding mass counterterms, and the effect of inter-generation mixing on their determination are discussed.
• Invoking the Aoki-Hioki-Kawabe-Konuma-Muta renormalization conditions and employing a number of very useful relations from Matrix Algebra, we show explicitly that the renormalized dressed propagators satisfy important physical properties.
