Abstract

I describe a unified formalism for lattice fermions, in which the relativistic action of Wilson and the nonrelativistic and static actions appear as special cases. It is valid at all values of m_q a, including m_q a ≈ 1. In the limit m_q a ≪ 1 , the formulation reduces to the light quark action of Wilson. In the limit m_q a ≫ 1 , the formulation reduces to the nonrelativistic action of Thacker and Lepage, and to the static action of Eichten.
