小x值下部分子密度的Q^2演化和H1和ZEUS实验数据

Q^2-evolution of parton densities at small x values and H1 and ZEUS experimental data

A. V. Kotikov, B. G. Shaikhatdenov

摘要:

研究表明,在Wilson算子乘积展开的首扭近似中,考虑到结构函数F ~ 2和导数d ln F ~ 2/f的Bessel启发行为,在具有“冻结”和解析强耦合常数的情况下,(dln(1/x)),在小的x值下,对于DGstrom演化方程中的平坦初始条件获得,与HERA的深度非弹性散射H1和ZEUS实验数据吻合较好

英文摘要:

It is shown that in the leading twist approximation of the Wilson operator product expansion with "frozen" and analytic strong coupling constants, considering the Bessel-inspired behavior of the structure functions F2 and the derivative d ln F2/(d ln(1/x)) at small x values, obtained for a flat initial condition in the DGLAP evolution equations,leads to a good agreement with the deep inelastic scattering H1 and ZEUS experimental data from HERA
