Higgs Transverse-Momentum Resummation in Direct Space.
We propose a new approach to the resummation of the transverse-momentum distribution of a high-mass color-singlet system in hadronic collisions. The resummation is performed in momentum space and is free of kinematic singularities at small transverse momentum. We derive a formula accurate at the next-to-next-to-leading-logarithmic level, and present the first matched predictions to next-to-next...
متن کاملTransverse-momentum Resummation at Hadron Colliders *
The inclusive production of colourless high-mass systems in hadron collisions is important for physics studies within and beyond the standard model. Well know examples of these processes are the production of lepton pairs, vector boson pairs, Higgs particles and so forth. These processes are either benchmark processes, whose expected rates should be precisely known, or irreducible backgrounds f...
متن کاملTransverse-Momentum Resummation for Slepton-Pair Production at the LHC
We perform a first precision calculation of the transverse-momentum (qT ) distribution of slepton pair and slepton-sneutrino associated production at the CERN Large Hadron Collider (LHC). We implement soft-gluon resummation at the next-to-leading logarithmic (NLL) level and consistently match the obtained result to the pure fixed-order perturbative result at leading order (LO) in the QCD coupli...
متن کاملTransverse-momentum resummation for top-quark pairs at hadron colliders.
We develop a framework for a systematic resummation of the transverse momentum distribution of top-quark pairs produced at hadron colliders based on effective field theory. Compared to Drell-Yan and Higgs production, a novel soft function matrix is required to account for the soft gluon emissions from the final states. We calculate this soft function at the next-to-leading order, and perform th...
متن کاملHiggs boson production at the LHC: transverse-momentum resummation and rapidity dependence
We consider Higgs boson production by gluon fusion in hadron collisions. We study the doubly-differential transverse-momentum (qT ) and rapidity (y) distribution of the Higgs boson in perturbative QCD. In the region of small qT (qT ≪ MH , MH being the mass of the Higgs boson), we include the effect of logarithmicallyenhanced contributions due to multiparton radiation to all perturbative orders....
