Exact Matching Condition for Matrix Elements in Lattice and MS Schemes
Xiangdong Ji
Abstract
The exact matching condition is given for hadron matrix elements calculated in any two different schemes, in particular, in the lattice and dimensional regularization, (modified) minimal subtraction MS schemes. The result provides insight into and permits to go beyond Lepage and Mackenzie's mean field theory of removing tadpole contributions in lattice operators.
