Flowed quark field renormalization in lattice QCD: A Ward-identity approach and its validation using quark bilinears

Mei-Qi Gao, Long-cheng Gui, Jun Hua +2

We present a non-perturbative Ward-identity prescription for determining the flowed quark field renormalization factor $Z_{χ}$ , avoiding the computational difficulties of the convent…

Direct lattice QCD calculation of the $θ$ -induced CP-violating pion-nucleon coupling

Chuan-Yang Li, Jun Hua, Jian Liang +4

We present the first direct lattice QCD determination of the $θ$ -induced CP-violating pion-nucleon-nucleon coupling $g ~_{π N N}$ . Using overlap valence fermions on three $2 + 1$ -…

Radiative decay of heavy-light mesons from lattice QCD

Wen-Zheng Hou, Nan Wang, Long-Cheng Gui +4

We present the first systematic study of the radiative decays of charmed mesons using $2 + 1$ -flavor clover fermion gauge ensembles generated by the CLQCD collaboration. One of the e…

$η$ and $η^{'}$ mesons from $N_{f} = 2 + 1$ lattice QCD at the physical point using topological charge operators

Yue Su, Nan Wang, Long-cheng Gui +3

By fitting the two-point correlation functions of topological charge density operators calculated on two $2 + 1$ -flavor gauge ensembles with physical pion mass, we determine both the…

Revisiting $C$ and $C P$ Violation in $η \to π^{+} π^{-} π^{0}$ Decay

Jun Shi, Jian Liang, Susan Gardner

The decay $η \to π^{+} π^{-} π^{0}$ is an ideal process in which to study flavor-conserving $C$ and $C P$ violation beyond the Standard Model. We deduce the $C$ - and $C P$ -odd quark operators…

Fast Fermion Smearing Scheme with Gaussian-like Profile

ChuanYang Li, Terrence Draper, Jun Hua +5

We propose a novel smearing scheme which gives a Gaussian-like profile and is more efficient than the traditional Gaussian smearing in terms of computer time consumption. We also c…
