Proper-time evaluation of the effective action: unequal masses in the loop
A. A. Osipov
The Fock-Schwinger proper-time method is used to derive the effective action in the field theory with the chiral symmetry explicitly broken by unequal masses of h…

Proper-time method for unequal masses
A. A. Osipov
The result of removing of heavy non-equal mass particles from the theory can be described, at low energy, by the effective action, which is a series in inverse-square powers of the…
