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

Joint two-dimensional resummation in q T and 0-jettiness at NNLL
Journal 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 $$ {\mathcal{T}}_0 $$ .

Uncovering Hidden Patterns: Approximate Resurgent Resummation from Truncated Series
MathematicsWe 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 ...

Resummed Results for Hadron Collider Observables
EPJ 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 ...

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

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

HERA data and collinearly-improved BK dynamics
Physics Letters B, 2020 Within the framework of the dipole factorisation, we use a recent collinearly-improved version of the Balitsky-Kovchegov equation to fit the HERA data for inclusive deep inelastic scattering at small Bjorken x.

High energy resummed predictions for the production of a Higgs boson with at least one jet
Journal of High Energy Physics, 2023 We present all-order predictions for Higgs boson production plus at least one jet which are accurate to leading logarithm in s ̂ / p ⊥ 2 $$ \hat{s}/{\left|{p}_{\perp}\right|}^2 $$ .

Pseudo and quasi quark PDF in the BFKL approximation
Journal 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.

First subleading power resummation for event shapes [PDF]
Journal of High Energy Physics, 2018 A bstractWe derive and analytically solve renormalization group (RG) equations of gauge invariant non-local Wilson line operators which resum logarithms for event shape observables τ at subleading power in the τ ≪ 1 expansion.
