"Automatic Computation of the Soft Anomalous Dimension Matrices for the 
Heavy Quark Hadroproduction"


     címmel tartandó szemináriumára.


Kivonat:



In this work we present the tools, which were developed to automatize 
the calculation of the soft anomalous dimension matrices for the heavy 
quark hadroproduction processes at one- and two-loop accuracy in QCD. 
The computation of the soft anomalous dimension matrices represent one 
of the major technical challenges in the resummation formalism to 
next–to–leading logarithmic and next–to–next–to–leading logarithmic 
accuracy, involving multiple colored massive states. The tools developed 
in this project, WilsonWebs and FORMSoft make it possible to perform 
such calculations fully automatically in an userfriendly manner. The 
application of these tools is demonstrated on the examples of t\bar{t}j 
and t\bar{t}t\bar{t} hadroproductions, making the step forward towards 
implementing a procedure for the resummation of soft-gluon emission 
logarithms for these processes.
