Nonsinglet parton distribution functions from the precise next-to-next-to-next-to leading order QCD fit

Ali N. Khorramian, H. Khanpour, S. Atashbar Tehrani

We present the results of our QCD analysis for non-singlet unpolarized quark distributions and structure function $F_2(x,Q^2)$ up to N${}^3$LO. In this regards 4-loop anomalous dimen…
