A numerical formulation of resummation in effective field theory
Journal 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.

How much joint resummation do we need?
Journal of High Energy Physics, 2019 Large logarithms that arise in cross sections due to the collinear and soft singularities of QCD are traditionally treated using parton showers or analytic resummation.

Momentum conservation and unitarity in parton showers and NLL resummation
Journal of High Energy Physics, 2018 We present a systematic study of differences between NLL resummation and parton showers. We first construct a Markovian Monte-Carlo algorithm for resummation of additive observables in electron-positron annihilation.

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.

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 ...

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 ...

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 ...
