Search for new particles in events with one lepton and missing transverse momentum in pp collisions at s√ = 8 TeV with the ATLAS detector [PDF]
, 2014 This paper presents a search for new particles in events with one lepton (electron or muon) and missing transverse momentum using 20.3 fb−1 of proton-proton collision data at s√ = 8 TeV recorded by the ATLAS experiment at the Large Hadron Collider.

Next-to-leading power two-loop soft functions for the Drell-Yan process at threshold
Journal of High Energy Physics, 2021 We calculate the generalized soft functions at O $$ \mathcal{O} $$ ( α s 2 $$ {\alpha}_s^2 $$ ) at next-to-leading power accuracy for the Drell-Yan process at threshold.

Symmetric ϵ- and (ϵ + 1/2)-forms and quadratic constraints in “elliptic” sectors.
Journal of High Energy Physics, 2018 Within the differential equation method for multiloop calculations, we examine the systems irreducible to ϵ-form. We argue that for many cases of such systems it is possible to obtain nontrivial quadratic constraints on the coefficients of ϵ-expansion of

Mass dependence of Higgs production at large transverse momentum
Journal of High Energy Physics, 2017 The transverse momentum distribution of the Higgs at large P T is complicated by its dependence on three important energy scales: P T , the top quark mass m t , and the Higgs mass m H .

Journal of High Energy Physics, 2017 We calculate a class of three-loop Feynman diagrams which contribute to the next-to-next-to-leading logarithmic approximation for the width difference ΔΓ s in the B s − B ¯ s $$ {B}_s-{\overline{B}}_s $$ system.

NLO QCD+EW corrections to diphoton production in association with a vector boson
Journal of High Energy Physics, 2018 Processes with three external electroweak gauge boson allow for a measurement of triple and quartic gauge couplings. They can be used to constrain anomalous gauge couplings, where new physics might predominantly couple to electroweak gauge bosons.

Resonace-improved parton-shower matching for the Drell-Yan process including electroweak corrections
Journal of High Energy Physics, 2017 We use the Powheg method to perform parton-shower matching for Drell-Yan production of W and Z bosons at the LHC at NLO QCD and NLO electroweak accuracy. In particular, we investigate an improved treatment of the vector-boson resonances within the Powheg
