We present results for the unpolarized parton distribution function of nucleon computed in lattice QCD at physical pion mass. This is first study its kind employing method Ioffe time pseudo-distributions. Beyond reconstruction Bjorken-$x$ dependence we also extract lowest moments using small expansion pseudo-distribution. compare our findings with pertinent phenomenological determinations.
