Update on flavor diagonal nucleon charges from clover fermions
Proceedings of The 40th International Symposium on Lattice Field Theory — PoS(LATTICE2023)(2024)
摘要
We present a summary of the full calculation of the axial, scalar and tensor
flavor diagonal charges of the nucleon carried out using Wilson-clover fermions
on eight ensembles generated using 2+1+1-flavors of highly improved staggered
quarks (HISQ) by the MILC collaboration. We also give results for the 3×
3 matrix of renormalization factors between the RI-sMOM and MS scheme for the 2+1 flavor theory that include flavor mixing. Preliminary
results for g_A,S,T^u,d,s are presented in the MS scheme
at scale 2 GeV.
