Abstract:

We present up-to-date Standard Model theory predictions for the Higgs transverse-momentum (pâŠ1) distribution. In the region of intermediate values of transverse momenta we present the NNLL+NLO QCD predictions including both top and bottom quark contributions. At very large pâŠ1 2mtwe show the next-to-leading order QCD corrections to the production of the Higgs boson at the LHC.

Abstract:

We study an elliptic generalization of multiple polylogarithms that appears naturally in the computation of the imaginary part of the two-loop massive sunrise graph with equal masses. The newly introduced functions fulfil non-homogeneous second order differential equations. As an important result, we introduce a concept of weight associated to the action of the second order differential operator and show how to classify the relations between the functions bottom up in their weight.
