DESCRIPTION:Speakers: 美琪 高 (华南师范大学)\nThe field renormali
 zation constant of flowed quark fields\, denoted as $Z_\\chi$\, is a criti
 cal component in the non-perturbative renormalization of fermion operators
  within the gradient flow framework. While the conventional ``ringed'' sch
 eme based on the fermion kinetic term provides a theoretically robust defi
 nition\, its practical implementation on the lattice is hampered by signif
 icant statistical noise arising from disconnected contributions. In this w
 ork\, we propose a novel approach to determine $Z_\\chi$ using quark bilin
 ears. To validate our approach\, we use the extracted $Z_\\chi$ to reconst
 ruct the renormalized bilinear matrix elements $O^R$ for the pseudoscalar\
 , scalar\, axial-vector\, and tensor channels in the continuum limit.Our r
 esults demonstrate excellent consistency between the gradient flow and RI/
 MOM frameworks\, confirming that the bilinear-based $Z_\\chi$ provides a r
 eliable and computationally efficient alternative for high-precision latti
 ce QCD calculations.\n\nhttps://indico.itp.ac.cn/event/437/contributions/2
