Jet broadening in flowing matter: Resummation [PDF]
Physical Review D, 2022 In this work, we obtain the leading corrections to the jet momentum broadening distribution in a QCD medium arising from the transverse flow of the matter.

Robust approach to thermal resummation: Standard Model meets a singlet [PDF]
Journal of High Energy Physics, 2021 Perturbation theory alone fails to describe thermodynamics of the electroweak phase transition. We review a technique combining perturbative and non-perturbative methods to overcome this challenge.

Classical Resummation and Breakdown of Strong-Field QED. [PDF]
Physical Review Letters, 2021 QED perturbation theory has been conjectured to break down in sufficiently strong backgrounds, obstructing the analysis of strong-field physics. We show that the breakdown occurs even in classical electrodynamics, at lower field strengths than previously

Rethinking jets with energy correlators: Tracks, resummation, and analytic continuation [PDF]
Physical Review D, 2020 We introduce an infinite set of jet substructure observables, derived as projections of $N$-point energy correlators, that both are convenient for experimental studies and maintain remarkable analytic properties derived from their representations in ...

High-energy resummation in $$\Lambda _c$$ baryon production [PDF]
, 2021 We present a study on inclusive emissions of a double Λc or of a Λc plus a light-flavored jet system as probe channels in the semi-hard regime of QCD. Our formalism relies on the so-called hybrid high-energy/collinear factorization, where the standard ...

Reduction of order, resummation, and radiation reaction [PDF]
Physical Review D, 2021 The Landau-Lifshitz equation is the first in an infinite series of approximations to the Lorentz-Abraham-Dirac equation obtained from `reduction of order'.

Medium-induced gluon radiation with full resummation of multiple scatterings for realistic parton-medium interactions [PDF]
Journal of High Energy Physics, 2020 The new precision era of jet quenching observables at both RHIC and the LHC calls for an improved and more precise description of in-medium gluon emissions. The development of new theoretical tools and analytical calculations to tackle this challenge has

Soft Anomalous Dimensions and Resummation in QCD
Universe, 2020 I discuss and review soft anomalous dimensions in QCD that describe soft-gluon threshold resummation for a wide range of hard-scattering processes. The factorization properties of the cross section in moment space and renormalization-group evolution are ...

Resummation of threshold logarithms in deeply-virtual Compton scattering
Journal of High Energy Physics, 2023 I derive an all-order resummation formula for the logarithmically enhanced contributions proportional to α s n x ± ξ $$ \frac{\alpha_s^n}{x\pm \xi } $$ log ξ ± x 2 ξ k $$ {\left(\frac{\xi \pm x}{2\xi}\right)}^k $$ in the quark coefficient function of ...

Resummation of Quantum Radiation Reaction in Plane Waves. [PDF]
Physical Review Letters, 2021 We propose a new approach to obtain the momentum expectation value of an electron in a high-intensity laser, including multiple photon emissions and loops.
