Resummation of threshold logarithms in deeply-virtual Compton scattering

open access: yesJournal 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 ...

Transverse-momentum resummation for boson plus jet production at hadron colliders [PDF]

open access: yesEuropean 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 ...

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.

On Using the BMCSL Equation of State to Renormalize the Onsager Theory Approach to Modeling Hard Prolate Spheroidal Liquid Crystal Mixtures [PDF]

open access: yesEntropy, 2021
Modifications to the traditional Onsager theory for modeling isotropic–nematic phase transitions in hard prolate spheroidal systems are presented. Pure component systems are used to identify the need to update the Lee–Parsons resummation term.

Momentum-space resummation for transverse observables and the Higgs p⊥ at N3LL+NNLO

open access: yesJournal 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.

Soft Anomalous Dimensions and Resummation in QCD

open access: yesUniverse, 2020
I discuss and review soft anomalous dimensions in QCD that describe soft-gluon threshold resummation for a wide range of hard-scattering processes. The factorization properties of the cross section in moment space and renormalization-group evolution are ...

Critical exponents of the O(N)-symmetric $$\phi ^4$$ ϕ 4 model from the $$\varepsilon ^7$$ ε 7 hypergeometric-Meijer resummation

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We extract the $$\varepsilon $$ ε -expansion from the recently obtained seven-loop g-expansion for the renormalization group functions of the O(N)-symmetric model.

NNLL resummation of Sudakov shoulder logarithms in the heavy jet mass distribution

open access: yesJournal of High Energy Physics, 2023
The heavy jet mass event shape has large perturbative logarithms near the leading order kinematic threshold at ρ = 1 3 $$ \rho =\frac{1}{3} $$ . Catani and Webber named these logarithms Sudakov shoulders and resummed them at double-logarithmic level.

QCD resummation in hard diffractive dijet production at the electron-ion collider

open access: yesPhysics Letters B, 2020
Diffractive dijet production at the electron-ion collider (EIC) has been proposed to study the gluon Wigner distribution at small-x. We investigate the soft gluon radiation associated with the final state jets and an all order resummation formula is ...

Parton distributions with small-x resummation: evidence for BFKL dynamics in HERA data

open access: yesEuropean 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 $$\hbox {NLO+NLL}x$$
