Color Superconducting Gap in Schwinger-Dyson Equation and Nonlocal Gauge Fixing
Chaejun Song (Seoul Nat'l U.)🇰🇷
Abstract
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 prefactor increases about 1.6 times to the leading order gap determined in Landau gauge.
