Chiral logs in the presence of staggered flavor symmetry breaking

  • 1. Washington University, St. Louis, Missouri 63130 (United States)

Description

Chiral logarithms in mπ2 are calculated at one loop, taking into account the leading contributions to flavor symmetry breaking due to staggered fermions. I treat both the full QCD case (2+1 light dynamical flavors) and the quenched case; finite volume corrections are included. My starting point is the effective chiral Lagrangian introduced by Lee and Sharpe. It is necessary to understand the one-loop diagrams in the 'quark flow' picture in order to adjust the calculation to correspond to the desired number of dynamical quarks
