چکیده
|
We show that already at the nlo level the dglap evolution kernel p qq starts to depend on the choice of the evolution variable. we give an explicit example of such a variable, namely the maximum of transverse momenta of emitted partons and we identify a class of evolution variables that leave the nlo p qq kernel unchanged with respect to the known standard $$ overline{mathrm{ms}} $$ results. the kernels are calculated using a modified curci-furmanski-petronzio method which is based on a direct feynman-graphs calculation.
