QCD resummation in hard diffractive dijet production at the electron-ion collider
Physics Letters B, 2020 Diffractive dijet production at the electron-ion collider (EIC) has been proposed to study the gluon Wigner distribution at small-x. We investigate the soft gluon radiation associated with the final state jets and an all order resummation formula is ...

Phenomenology of combined resummation for Higgs and Drell-Yan
Journal of High Energy Physics, 2020 We study the phenomenological impact of a recently suggested formalism for the combination of threshold and a so-called threshold-improved transverse momentum resummation, by using it to improve the fixed-order results.

A numerical formulation of resummation in effective field theory
Journal of High Energy Physics, 2019 In this article we show how the resummation of infrared and collinear logarithms within Soft-Collinear Effective Theory (SCET) can be formulated in a way that makes it suitable for a Monte-Carlo implementation.

Drell-Yan qT resummation of fiducial power corrections at N3LL [PDF]
Journal of High Energy Physics, 2020 We consider Drell-Yan production pp → V*X → LX at small qT ≪ Q, where qT and Q are the total transverse momentum and invariant mass of the leptonic final state L.

How much joint resummation do we need?
Journal of High Energy Physics, 2019 Large logarithms that arise in cross sections due to the collinear and soft singularities of QCD are traditionally treated using parton showers or analytic resummation.

Infrared resummation for biased tracers in redshift space [PDF]
Journal of Cosmology and Astroparticle Physics, 2018 We incorporate the effects of redshift space distortions and non-linear bias in time-sliced perturbation theory (TSPT). This is done via a new method that allows to map cosmological correlation functions from real to redshift space.

De Sitter diagrammar and the resummation of time [PDF]
Journal of High Energy Physics, 2019 Light scalars in inflationary spacetimes suffer from logarithmic infrared divergences at every order in perturbation theory. This corresponds to the scalar field values in different Hubble patches undergoing a random walk of quantum fluctuations, leading

Momentum conservation and unitarity in parton showers and NLL resummation
Journal of High Energy Physics, 2018 We present a systematic study of differences between NLL resummation and parton showers. We first construct a Markovian Monte-Carlo algorithm for resummation of additive observables in electron-positron annihilation.

Resummation and Simulation of Soft Gluon Effects beyond Leading Color. [PDF]
Physical Review Letters, 2020 We present first results of resumming soft gluon effects in a simulation of high-energy collisions beyond the leading-color approximation. We work to all orders in QCD perturbation theory using a new parton branching algorithm.

Groomed jet mass at high precision
Physics 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 ...
