An Effective Field Theory at Finite Density
Masayasu Harada, Dong-Pil Min, Tae-Sun Park +2
An effective theory to treat the dense nuclear medium by the perturbative expansion method is proposed as a natural extension of the Heavy Baryon Chiral Perturbation Theory (HBChPT…

Color Superconducting Gap in Schwinger-Dyson Equation and Nonlocal Gauge Fixing
Chaejun Song
We solve Schwinger-Dyson (SD) equation for the color superconducting (CS) gap in nonlocal gauge which justifies the ladder approximation in subleading order calculation. The gap pr…

Higher order corrections to Color superconducting gaps
Deog Ki Hong, Taekoon Lee, Dong-Pil Min +2
We find a (nonlocal) gauge where the wavefunction renormalization constant does not get any corrections for all momenta in the hard-dense loop approximation. In this gauge, we solv…
