DOI: 10.1007/jhep02(2018)108
Abstract: A bstractWe present an approach to the momentum-space resummation of global, recursively infrared and collinear safe observables that can vanish away from the Sudakov region. We focus on the hadro-production of a generic colour singlet,… read more here.

Abstract: A bstractWe consider Drell-Yan production pp → Z/γ∗ → ℓ+ℓ− with the simultaneous measurement of the Z-boson transverse momentum qT and 0-jettiness T0$$ {\mathcal{T}}_0 $$. Since both observables resolve the initial-state QCD radiation, the double-differential… read more here.

DOI: 10.1007/jhep03(2019)149
Abstract: A bstractI present a sequence of non-perturbative approximate solutions for scalar ϕ4 theory for arbitrary interaction strength, which contains, but allows to systematically improve on, the familiar mean-field approximation. This sequence of approximate solutions is… read more here.

DOI: 10.1007/s00601-018-1417-4
Abstract: Large perturbative corrections, which appear in perturbative expressions for many QCD observables, either at small $$Q_T$$QT or at partonic threshold, can be organized by way of all order resummation. Joint resummation allows simultaneous resummation of… read more here.

DOI: 10.1088/1475-7516/2020/03/018
Abstract: We develop an analytic method for implementing the IR-resummation of arXiv:1404.5954, which allows one to correctly and consistently describe the imprint of baryon acoustic oscillations (BAO) on statistical observables in large-scale structure. We show that… read more here.

Enhanced threshold resummation formalism for lepton pair production and its effects in the determination of parton distribution functions
Sign Up to like & getrecommendations! Published in 2017 at "Physical Review D"
DOI: 10.1103/physrevd.95.056024
Abstract: We demonstrate that theoretical predictions using current resummation techniques for the lepton pair production (LPP) rapidity and $x_F$ distributions can be inconsistent with data in high rapidity and $x_F$ kinematic regions by observing their effect… read more here.
