Description

We consider impact of the large-log resummation emerging at the large momentum transfer $Q$ in the variable-flavour-number (VFN) scheme description when it is applied to analysis of the semi-inclusive DIS production of the charm and bottom quarks. Matching of the VFN scheme with the fixed-flavour-number (FFN) one at small $Q$ is also discussed and phenomenological relevance of these two approaches at various $Q$ is compared.
