标题： The Strangeness and Charmness of Nucleon from Overlap Fermions

摘要： 用重叠费米子作用于2+1味域墙费米子构型上计算核子的奇异数和魅数值。 我们采用随机网格源以及低模式替代技术来改善核子相关函数和环路的信号。 计算是在一个$24^3\times 64$晶格上完成的，其中包含$m_l=0.005$，$m_h=0.04$和$a^{-1}=1.73\,{\rm GeV}$。 我们发现$ f_{T_{s}} = 0.048(15)$和$f_{T_{c}} = 0.029(43)$。 显示英文摘要

摘要： The calculation of the strangeness and charmness of the nucleon is presented with overlap fermion action on 2+1 flavor domain wall fermion configurations. We adopt stochastic grid sources and the low mode substitution technique to improve the signals of nucleon correlation functions and the loops. The calculation is done on a $24^3\times 64$ lattice with $m_l=0.005$, $m_h=0.04$, and $a^{-1}=1.73\,{\rm GeV}$. We find $ f_{T_{s}} = 0.048(15)$ and $f_{T_{c}} = 0.029(43)$.
