摘要:An approach which unies the Double Logarithmic Approximation at small x and the leading
order DGLAP evolution of fragmentation functions at large x is presented. This approach reproduces
exactly the Modied Leading Logarithm Approximation, but is more complete due to
the degrees of freedom given to the quark sector and the inclusion of the xed order terms. We
nd that data from the largest x values to the peak region can be better tted than with other
approaches.
