PDF of Deuteron-like Di-baryon system on Lattice QCD

by Prof. Peng Sun (中科院近代物理所)

B105 (CHEP)




We apply the lattice QCD method to the calculation of the Deuteron-like dibaryon system parton distribution function. We perform our calculation on three types of ensembles with two pion masses and two space-time volumes. The quasi-matrix elements are computed with proton momenta up to 2.46 GeV and we improve the signal of high momentum modes by applying the momentum smearing method. The results are then renormalized in the hybrid scheme and matched to light-cone parton distribution using large-momentum effective theory (LaMET). Our final results open a window for the study of the nuclear effect.
