High Energy Physics - Phenomenology 2019-08-19 v1

Abstract

We present for first time the computation at large qTq_T (or small bTb_T) matching coefficients of Transverse Momentum Dependent Parton Distribution Function (TMDPDF) for linearly polarised to the integrated gluon distribution at next-to-next-to leading order (NNLO). The computation is performed using the modified δ\delta-regulator for rapidity divergences and dimensional regularization. This TMDPDF matriz element presnts phenomenological interest in two kind of processes. The factorization of the Higgs production transverse momentum (qTq_T) distribution through gluon-gluon fusion and the quarkonium production.
