Resummation of threshold logarithms in deeply-virtual Compton scattering
Journal of High Energy Physics, 2023 I derive an all-order resummation formula for the logarithmically enhanced contributions proportional to α s n x ± ξ $$ \frac{\alpha_s^n}{x\pm \xi } $$ log ξ ± x 2 ξ k $$ {\left(\frac{\xi \pm x}{2\xi}\right)}^k $$ in the quark coefficient function of ...

, 2005 We review the work discussed and developed under the topic ``Resummation'' at Working Group 2 ``Multijet final states and energy flow'', of the HERA-LHC Workshop. We emphasise the role played by HERA observables in the development of resummation tools via, for instance, the discovery and resummation of non-global logarithms.

PROGRESS IN SMALL x RESUMMATION [PDF]
International Journal of Modern Physics A, 2006 I review recent theoretical progress in the resummation of small x contributions to the evolution of parton distributions, in view of its potential significance for accurate phenomenology at future colliders. I show that a consistent perturbative resummation of collinear and energy logs is now possible, and necessary if one wishes to use recent NNLO ...

Transverse-momentum resummation for boson plus jet production at hadron colliders [PDF]
European Physical Journal C: Particles and Fields, 2022 We consider the associated production of a vector or Higgs boson with a jet in hadronic collisions. When the transverse momentum $$q_T$$ q T of the boson-jet system is much smaller than its invariant mass Q, the QCD perturbative expansion is affected by ...

NLL′ resummation of jet mass [PDF]
Journal of High Energy Physics, 2019 Abstract Starting from a factorization theorem in effective field theory, we present resummed results for two non-global observables: the invariant-mass distribution of jets and the energy distribution outside jets. Our results include the full next-to-leading-order corrections to the hard, jet and soft functions and are ...

A numerical formulation of resummation in effective field theory
Journal of High Energy Physics, 2019 In this article we show how the resummation of infrared and collinear logarithms within Soft-Collinear Effective Theory (SCET) can be formulated in a way that makes it suitable for a Monte-Carlo implementation.

Parton distributions with small-x resummation: evidence for BFKL dynamics in HERA data [PDF]
European Physical Journal C: Particles and Fields, 2018 We present a determination of the parton distribution functions of the proton in which NLO and NNLO fixed-order calculations are supplemented by NLLx small-x resummation. Deep-inelastic structure functions are computed consistently at $$\hbox {NLO+NLL}x$$

How much joint resummation do we need? [PDF]
Journal of High Energy Physics, 2019 Large logarithms that arise in cross sections due to the collinear and soft singularities of QCD are traditionally treated using parton showers or analytic resummation.
