Dependence of the current renormalisation constants on the quark mass
We study the behaviour of the vector and axial current renormalisation constants Z_V and Z_A as a function of the quark mass, m_q. We show that sizeable O(am_q) and O(g_0^2 a m_q) systematic effects are present in the Wilson and Clover cases respectively. We find that the prescription of Kronfeld, L...
