Transverse-momentum resummation for boson plus jet production at hadron colliders. [PDF]
Eur Phys J C Part 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

Parton distributions with small-x resummation: evidence for BFKL dynamics in HERA data. [PDF]
Eur Phys J C Part 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.

Borel resummation of secular divergences in stochastic inflation [PDF]
Journal of High Energy Physics, 2023 We make use of Borel resummation to extract the exact time dependence from the divergent series found in the context of stochastic inflation. Correlation functions of self-interacting scalar fields in de Sitter spacetime are known to develop secular IR ...

Next-to-leading-logarithm k resummation for B → J/ψ decays [PDF]
Physics Letters B, 2020 We derive the $k_T$ resummation for a transverse-momentum-dependent charmonium wave function, which involves the bottom quark mass $m_b$, the charm quark mass $m_c$, and the charm quark transverse momentum $k_T$, up to the next-to-leading-logarithm (NLL)

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

Event-based transverse momentum resummation. [PDF]
Eur Phys J C Part Fields, 2019 We have developed a framework for automated transverse momentum resummation for arbitrary electroweak final states based on reweighting tree-level events.

High-energy resummation in heavy-quark pair hadroproduction [PDF]
European Physical Journal C: Particles and Fields, 2019 The inclusive hadroproduction of two heavy quarks, featuring a large separation in rapidity, is proposed as a novel probe channel of the Balitsky–Fadin–Kuraev–Lipatov (BFKL) approach.
