The variable flavor number scheme at nexttoleading order
/ Blümlein, J. ; De Freitas, A. ; Schneider, C. ; Schönwald, K.
We present the matching relations of the variable flavor number scheme at nexttoleading order, which are of importance to define heavy quark partonic distributions for the use at high energy colliders such as Tevatron and the LHC. [...]
