DESCRIPTION:Speakers: 春华 曾 ()\nWe report a state-of-the-art lattice 
 QCD calculation of the nucleon unpolarized gluon parton dis-\ntribution fu
 nction employing large-momentum effective theory. The calculation is carri
 ed out on the\n2+1 flavor CLQCD ensembles with five lattice spacings a = {
 0.105\, 0.0897\, 0.0775\, 0.0688\, 0.0519}\nfm and various pion masses ran
 ging from 136 MeV to 317 MeV\, covering nulceon momenta up to 3\nGeV. Dist
 illation technique is applied to improve the signal of two-point correlato
 rs. We then apply\nthe state-of-the-art hybrid renormalization and one-loo
 p perturbative matching\, and extrapolate\nthe result to the continuum lim
 it\, infinite momentum limit and physical pion mass.\n\nhttps://indico.itp
