Instanton Determinant with Arbitrary Quark Mass: WKB Phase-shift Method and Derivative Expansion
Gerald V. Dunne, Jin Hur, Choonkyu Lee +1
The fermion determinant in an instanton background for a quark field of arbitrary mass is studied using the Schwinger proper-time representation with WKB scattering phase shifts fo…

On mass dependences of the one-loop effective action in simple backgrounds
O-Kab Kwon, Choonkyu Lee, Hyunsoo Min
If background fields are soft on the scale set by mass of the particle involved, a reliable approximation to the field-theoretic one-loop effective action is obtained by a systemat…
