Groomed jet mass at high precision
Physics Letters B, 2020 We present predictions of the distribution of groomed heavy jet mass in electron-positron collisions at the next-to-next-to-leading order accuracy matched with the resummation of large logarithms to next-to-next-to-next-to-leading logarithmic accuracy ...

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.

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.

Borel resummation of secular divergences in stochastic inflation
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 ...

Non-global logarithms and jet algorithms in high-pT jet shapes [PDF]
, 2010 We consider jet-shape observables of the type proposed recently, where the shapes of one or more high-pT jets, produced in a multi-jet event with definite jet multiplicity, may be measured leaving other jets in the event unmeasured.

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.

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 ...

Transverse-momentum resummation and the spectrum of the Higgs boson at the LHC [PDF]
, 2005 We consider the transverse-momentum (q_T) distribution of generic high-mass systems (lepton pairs, vector bosons, Higgs particles, ....) produced in hadron collisions.

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 ...
