QUARK MASS RENORMALIZATION IN LATTICE GAUGE THEORY (Ⅰ) STRONG COUPLING REGION AND CROSSOVER REGION

  • The light quark mass m(g) is renormalized by fixing the ρ meson mass. m(g) for g≥2 is obtained by strong coupling expansion. Variatonal calculation extends m(g) to g~1, which is already in the crossover region. The two methods agree in the strong coupling region. In the crossover gegion, m(g) drops quickly towards the weak coupling value.

QUARK MASS RENORMALIZATION IN LATTICE GAUGE THEORY (Ⅰ) STRONG COUPLING REGION AND CROSSOVER REGION

    Corresponding author: GUO Shuo-Hong,

Abstract: The light quark mass m(g) is renormalized by fixing the ρ meson mass. m(g) for g≥2 is obtained by strong coupling expansion. Variatonal calculation extends m(g) to g~1, which is already in the crossover region. The two methods agree in the strong coupling region. In the crossover gegion, m(g) drops quickly towards the weak coupling value.
