New type of parametrizations for parton distributions

A. Yu. Illarionov, A. V. Kotikov, S. S. Parzycki, D. V. Peshekhonov

摘要:

基于价夸克部分子分布函数在大、小x值下的Q^2演化,构造了一种新的参数化形式。它精确地保持了DG方程解的低x和大x渐近性,并遵守Gross-Llewellyn-Smith求和规则。

英文摘要:

New type of parametrization for parton distribution functions, based on an exact their Q^2-evolution at large and small x values, is constructed for valence quarks. It preserves exactly the low x and large x asymptotics of the solution of the DGLAP equation and obeys the Gross-Llewellyn-Smith sum rule.
