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 ...

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

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 $$\hbox {NLO+NLL}x$$

Impact of low-x resummation on QCD analysis of HERA data [PDF]
European Physical Journal C: Particles and Fields, 2018 Fits to the final combined HERA deep-inelastic scattering cross-section data within the conventional DGLAP framework of QCD have shown some tension at low x and low $$Q^2$$ Q2 .

Soft Anomalous Dimensions and Resummation in QCD
Universe, 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 ...

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 ...

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

Sudakov Logarithm Resummation in Transverse Momentum Space for Electroweak Boson Production at Hadron Colliders [PDF]
, 1999 A complete description of W and Z boson production at high-energy hadron colliders requires the resummation of large Sudakov double logarithms which dominate the transverse momentum (q_T) distribution at small q_T.
