Next-to-leading-logarithm threshold resummation for exclusive B meson decays
European Physical Journal C: Particles and Fields, 2021 We extend the threshold resummation of the large logarithms $$\ln x$$ ln x which appear in factorization formulas for exclusive B meson decays, x being a spectator momentum fraction, to the next-to-leading-logarithm (NLL) accuracy.

Resummation methods for Master Integrals [PDF]
Journal of High Energy Physics, 2020 We present in detail two resummation methods emerging from the application of the Simplified Differential Equations approach to a canonical basis of master integrals.

Hadron-in-jet production at partonic threshold
Journal of High Energy Physics, 2020 We consider the longitudinal momentum distribution of hadrons inside jets in proton-proton collisions. At partonic threshold large double logarithmic corrections arise which need to be resummed to all orders.

Higgs Transverse Momentum with a Jet Veto: A Double-Differential Resummation. [PDF]
Physical Review Letters, 2019 We consider the simultaneous measurement of the Higgs (p_{t}^{H}) and the leading jet (p_{t}^{J}) transverse momentum in hadronic Higgs-boson production, and perform the resummation of the large logarithmic corrections that originate in the limit p_{t ...

Journal of High Energy Physics, 2021 The resummation of radiative corrections to collider jet observables using soft collinear effective theory is encoded in differential renormalization group equations (RGEs), with anomalous dimensions depending on the observable under consideration.

Diagrammatic resummation of leading-logarithmic threshold effects at next-to-leading power [PDF]
Journal of High Energy Physics, 2019 Perturbative cross-sections in QCD are beset by logarithms of kinematic invariants, whose arguments vanish when heavy particles are produced near threshold.

Resummation for 2→n processes in single-particle-inclusive kinematics [PDF]
, 2020 We present a formalism and detailed analytical results for soft-gluon resummation for $2\rightarrow n$ processes in single-particle-inclusive (1PI) kinematics.

Leading Logarithm Quantum Gravity
UniverseThe continual production of long wavelength gravitons during primordial inflation endows graviton loop corrections with secular growth factors. During a prolonged period of inflation, these factors eventually overwhelm the small loop-counting parameter ...

Small-x phenomenology at the LHC and beyond: HELL 3.0 and the case of the Higgs cross section
European Physical Journal C: Particles and Fields, 2018 Small-x resummation has been proven recently to be a crucial ingredient for describing small-x HERA data, and the inclusion of small-x resummation in parton distribution function (PDF) determination has a sizeable effect on the PDFs even at the ...

Matching resummed endpoint and continuum γ-ray spectra from dark-matter annihilation
Physics Letters B, 2022 For the minimal wino and Higgsino benchmark models we provide accurate energy spectra of high-energy photons from TeV scale dark-matter annihilation χχ→γ+X by merging electroweak Sudakov resummation near maximal energy with the electroweak parton-shower ...
