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.

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 ...

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 ...

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 ...

Electroweak resummation of neutralino dark-matter annihilation into high-energy photons

open access: yes, 2023
We consider the resummation of large electroweak Sudakov logarithms for the annihilation of neutralino DM with (TeV) mass to high-energy photons in the minimal supersymmetric standard model, extending previous work on the minimal wino and Higgsino models.

Joint two-dimensional resummation in q T and 0-jettiness at NNLL

open access: yesJournal of High Energy Physics, 2019
We consider Drell-Yan production pp → Z/γ ∗ → ℓ + ℓ − with the simultaneous measurement of the Z-boson transverse momentum q T and 0-jettiness T 0 $$ {\mathcal{T}}_0 $$ .

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 ...

Borel resummation of secular divergences in stochastic inflation

open access: yesJournal 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 ...
