The Resummation of One Particle Lines [PDF]

open access: yesCommunications in Mathematical Physics, 1979
We propose a partial resummation for a weak coupling cluster expansion. The resummation gives one particle lines with in/out field propagators. We give a Bethe-Salpeter equation in which one particle subtractions are defined using physical one particle states.

Hadron-in-jet production at partonic threshold

open access: yesJournal 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.

Groomed jet mass at high precision

open access: yesPhysics 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 ...

Analysis of the 3d massive renormalization group perturbative expansions: a delicate case

open access: yesCondensed Matter Physics, 2010
The effectiveness of the perturbative renormalization group approach at fixed space dimension d in the theory of critical phenomena is analyzed. Three models are considered: the O(N) model, the cubic model and the antiferromagnetic model defined on the ...

Uncovering Hidden Patterns: Approximate Resurgent Resummation from Truncated Series

open access: yesMathematics
We analyze truncated series generated as divergent formal solutions of non-linear ordinary differential equations. Motivating the study is a specific non-linear, first-order differential equation, which is the basis of the resurgent formulation of ...

Matching resummed endpoint and continuum γ-ray spectra from dark-matter annihilation

open access: yesPhysics 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 ...

A new prescription for soft gluon resummation

open access: yes, 2007
We present a new prescription for the resummation of the divergent series of perturbative corrections, due to soft gluon emission, to hard processes near threshold in perturbative QCD (threshold resummation).

Next-to-leading-logarithm kT resummation for Bc → J/ψ decays

open access: yesPhysics Letters B, 2020
We derive the kT resummation for a transverse-momentum-dependent charmonium wave function, which involves the bottom quark mass mb, the charm quark mass mc, and the charm quark transverse momentum kT, up to the next-to-leading-logarithm (NLL) accuracy ...
