reSolve — A transverse momentum resummation tool [PDF]
Computer Physics Communications, 2019 In this note, we introduce the new tool reSolve, a Monte Carlo differential cross-section and parton-level event generator whose main purpose is to add transverse momentum resummation to a general class of inclusive processes at hadron colliders, namely all those which do not involve hadrons or jets in the measured final state.

A new prescription for soft gluon resummation
, 2007 We present a new prescription for the resummation of the divergent series of perturbative corrections, due to soft gluon emission, to hard processes near threshold in perturbative QCD (threshold resummation).

Small-x resummation from HELL [PDF]
The European Physical Journal C, 2016 Small-$x$ logarithmic enhancements arising from high-energy gluon emissions affect both the evolution of collinearly-factorized parton densities and partonic coefficient functions. With the higher collider energy reached by the LHC, the prospect of a future high-energy collider, and the recent deep-inelastic scattering (DIS) results at small-$x$ from ...

Unification of the kT and threshold resummations [PDF]
Physics Letters B, 1999 We derive a resummation formula for a $k_T$-dependent parton distribution function at threshold, where $k_T$ is a parton transverse momentum. The derivation requires infrared cutoffs for both longitudinal and transverse loop momenta as evaluating soft gluon emissions in the Collins-Soper resummation framework.

Threshold resummation of semi-inclusive deep-inelastic scattering
European Physical Journal C: Particles and FieldsWe derive threshold resummation of semi-inclusive deep-inelastic scattering (SIDIS), by building upon previous results by some of us for the resummation of the Drell–Yan process at fixed rapidity, which is related to SIDIS by crossing. We consider both a

Parton distributions with threshold resummation [PDF]
, 2015 We construct a set of parton distribution functions (PDFs) in which fixed-order NLO and NNLO calculations are supplemented with soft-gluon (threshold) resummation up to NLL and NNLL accuracy respectively, suitable for use in conjunction with any QCD ...

Momentum-space resummation for transverse observables and the Higgs p ⊥ at N3LL+NNLO
Journal of High Energy Physics, 2018 We present an approach to the momentum-space resummation of global, recursively infrared and collinear safe observables that can vanish away from the Sudakov region.

Power corrections, renormalons and resummation [PDF]
, 1996 I briefly review three topics of recent interest concerning power corrections, renormalons and Sudakov resummation: (a) 1/Q corrections to event shape observables in e(+)e(-) annihilation, (b) power corrections in Drell-Yan production and (c) factorial ...

How Resummation Depresses the Gluon at Small x [PDF]
, 2006 We summarize recent progress in the resummation of perturbative evolution at small x. We show that the problem of incorporating BFKL small x logs in GLAP evolution is now completely solved, and that the main effect of small x resummation is to reduce the

Transverse momentum distributions at large-x
Journal of High Energy PhysicsWe investigate the collinear matching of transverse momentum dependent (TMD) distributions at large values of x, computing and resumming the leading large-x asymptotics for matching coefficients.
