Soft effects in transverse spectra at hadron colliders

Abstract:
The focus of my Master's thesis is the soft function of the top-quark pair production process at small
transverse momentum. The soft function describes the soft interaction and is one ingredient of the factorized cross-section formula that is derived in the soft-collinear effective theory (SCET). I present a short introduction into
SCET and show the main steps of the derivation of the factorization formula for the process of interest. The NLO
soft function contains tricky integrals. I present a powerful method for the systematic calculation of the NLO soft
function. Within this method it is possible to perform the calculation up to higher orders in epsilon which offers
a prediction for one finite NNLO contribution. On top of that, the integration method I present can be used as a
starting point for the calculation of the NNLO soft function.
