标题： DEPENDENCE OF THE CURRENT RENORMALISATION CONSTANTS ON THE QUARK MASS

摘要： 我们研究了矢量和轴向电流重整化常数$Z_V$和$Z_A$随夸克质量$m_q$的变化行为。 我们表明，在威尔逊和Clover情况下分别存在显著的$O(am_q)$和$O(g_0^2 a m_q)$系统效应。 我们发现，Kronfeld、Lepage 和 Mackenzie 用于校正这些伪像的方法并不总是有效。 显示英文摘要

摘要： 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, Lepage and Mackenzie for correcting these artefacts is not always successful.
