"Basis transformation properties of anomalous dimensions for hard exclusive 
processes”


címmel tartandó szemináriumára.


Kivonat:



The anomalous dimensions of composite QCD operators characterize the scale 
dependence of non-perturbative parton distributions. Their computation 
involves the renormalization of the partonic operator matrix elements and, in 
the context of hard exclusive scattering processes, requires one to take into 
account mixing with total-derivative operators. To deal with this issue, one 
can choose a suitable basis for the operators that simplifies certain aspects 
of the computation. In this talk we set up the explicit similarity 
transformations between two such bases which are well known in the 
literature. This way, one can use the properties of both bases to their 
advantage in the computation of the operator anomalous dimensions and perform 
valuable cross-checks of independent calculations. Several applications of 
our new transformation rule will also be discussed during the talk.
