The Resummation of Soft Gluon in Hadronic Collisions [PDF]

open access: yes, 1996
We compute the effects of soft gluon resummation for the production of high mass systems in hadronic collisions. We carefully analyse the growth of the perturbative expansion coefficients of the resummation formula.

Phenomenology of combined resummation for Higgs and Drell-Yan

open access: yesJournal of High Energy Physics, 2020
We study the phenomenological impact of a recently suggested formalism for the combination of threshold and a so-called threshold-improved transverse momentum resummation, by using it to improve the fixed-order results.

Associated $t \bar{t} H$ production at the LHC: theoretical predictions at NLO+NNLL accuracy [PDF]

open access: yes, 2017
We perform threshold resummation of soft gluon corrections to the total cross section and the invariant mass distribution for the process $pp \to t\bar{t}H$.

A numerical formulation of resummation in effective field theory

open access: yesJournal 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.

Soft Gluons in Logarithmic Summations [PDF]

open access: yes, 1999
We demonstrate that all the known single- and double-logarithm summations for a parton distribution function can be unified in the Collins-Soper resummation technique by applying soft approximations appropriate in different kinematic regions to real ...

Renormalization and resummation in finite temperature field theories [PDF]

open access: yes, 2004
Resummation, ie. reorganization of perturbative series, can result in an inconsistent perturbation theory, unless the counterterms are reorganized in an appropriate way.

How much joint resummation do we need?

open access: yesJournal 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.

Small x Resummation with Quarks: Deep-Inelastic Scattering [PDF]

open access: yes, 2008
We extend our previous results on small-x resummation in the pure Yang--Mills theory to full QCD with nf quark flavours, with a resummed two-by-two matrix of resummed quark and gluon splitting functions. We also construct the corresponding deep-inelastic

Momentum conservation and unitarity in parton showers and NLL resummation

open access: yesJournal of High Energy Physics, 2018
We present a systematic study of differences between NLL resummation and parton showers. We first construct a Markovian Monte-Carlo algorithm for resummation of additive observables in electron-positron annihilation.

Resummations in Hot Scalar Electrodynamics [PDF]

open access: yes, 1994
The gauge-boson sector of perturbative scalar electrodynamics is investigated in detail as a testing ground for resummation methods in hot gauge theories. It also serves as a simple non-trivial reference system for the non-Abelian gluon plasma.
