Timelike small x Resummation for Fragmentation Functions
Abstract
The status of small x resummation in the timelike kinematics is discussed. We present a general procedure to extract the large logarithms of x in the MS factorization scheme and to resum them in a closed form. New results for the doubly-logarithm-resummed coefficient functions will be reviewed. All our resummation formulae are in agrement with the fixed NNLO computations recently done by other groups in the MS scheme.
