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 ...

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 ...

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 $$ {\mathcal{T}}_0 $$ .

Disentangling observable dependence in SCETI and SCETII anomalous dimensions: angularities at two loops

open access: yesJournal 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.

Resummed Results for Hadron Collider Observables

open access: yesEPJ Web of Conferences, 2016
Event shapes are invaluable QCD tools for theoretical calculations and experimental measurements. We revise the definition of these observables in e+e− annihilation and in hadron collisions, and give a review of the state-of-the-art results for their ...

Associated production of a top quark pair with a heavy electroweak gauge boson at NLO+NNLL accuracy

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
We perform threshold resummation of soft gluon corrections to the total cross sections and the invariant mass distributions for production of a top-antitop quark pair associated with a heavy electroweak boson $$V = W^+$$ V=W+ , $$W^-$$ W- or Z in pp ...

Small-x phenomenology at the LHC and beyond: HELL 3.0 and the case of the Higgs cross section

open access: yesEuropean 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 ...

The light MSSM Higgs boson mass for large $$\tan \beta $$ tan β and complex input parameters

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
We discuss various improvements of the prediction for the light MSSM Higgs boson mass in the hybrid framework of the public code $$\texttt {FeynHiggs}$$ FeynHiggs , which combines fixed-order and effective field theory results.

Pseudo and quasi quark PDF in the BFKL approximation

open access: yesJournal of High Energy Physics, 2023
I examine the high-energy behavior of the Ioffe-time distribution for the quark bi-local space-like separated operator using the high-energy operator product expansion.

Threshold resummation of rapidity distributions at fixed partonic rapidity

open access: yesJournal of High Energy Physics
We derive a general expression for the resummation of rapidity distributions for processes with a colorless final state, such as Drell-Yan or Higgs production, in the limit in which the center-of-mass energy goes on threshold, but with fixed rapidity of ...
