论文摘要
本演讲提供了有关核子基态之间风味对角线轴向，标量和张Q Quark双线性算子的矩阵元素的计算的更新。模拟是使用MILC协作产生的八个2+1+1-Fravory HISQ的海洋上的Wilson-Clover Fermions进行的。我们在连接和断开的贡献，重新规定常数的计算和RI-SMOM方案中的混合中讨论了信号，并控制了用于提取最终指控的同时手性手性纤维 - 纤维纤维 - 纤维 - 纤维素体积拟合。
This talk provides an update on the calculation of matrix elements of flavor diagonal axial, scalar and tensor quark bilinear operators between the nucleon ground state. The simulations are done using Wilson-clover fermions on a sea of eight 2+1+1-flavor HISQ ensembles generated by the MILC collaboration. We discuss the signal in the connected and disconnected contributions, calculation of the renormalization constants and mixing in the RI-sMOM scheme, and control over the simultaneous chiral-continuum-finite-volume fit used to extract the final charges.
