A Study of PCAC for the Nonperturbative Improvement of the Wilson Action
Abstract
We present an exploratory study for the nonperturbative determination of the coefficient of the O(a) improvement term to the Wilson action, cSW. Following the work by L\"uscher et al., we impose the PCAC relation as a nonperturbative improvement condition on cSW, without, however, using the Schr\"odinger functional in our calculation.
