Vector boson production at hadron colliders : hard-collinear coefficients at the NNLO / S. Catani, L. Cieri, D. Florian, G. Ferrera, M. Grazzini. - In: THE EUROPEAN PHYSICAL JOURNAL. C, PARTICLES AND FIELDS. - ISSN 1434-6044. - 72:11(2012), pp. 2195.1-2195.9. [10.1140/epjc/s10052-012-2195-7]
Abstract:
We consider QCD radiative corrections to vector-boson production in hadron collisions. We present the next-to-next-to-leading order (NNLO) result of the hard-collinear coefficient function for the all-order resummation of logarithmically enhanced contributions at small transverse momenta. The coefficient function controls NNLO contributions in resummed calculations at full next-to-next-to-leading logarithmic accuracy. The same coefficient function is used in applications of the subtraction method to perform fully exclusive perturbative calculations up to NNLO.
