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.

Journal of Molecular Structure, 2018 Abstract Aspidospermidine is a member of the compound class known as aspidospermaten-type alkaloids. Aspidospermidine is among the most highly sought aspidosperma alkaloid targets because it comprises the basic skeletal features of this family of natural products, particularly the complex and characteristic pentacyclic ABCDE framework. In this study,

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

CompHEP 4.4 - Automatic Computations from Lagrangians to Events
, 2004 We present a new version of the CompHEP program (version 4.4). We describe shortly new issues implemented in this version, namely, simplification of quark flavor combinatorics for the evaluation of hadronic processes, Les Houches Accord based CompHEP ...

The automation of next-to-leading order electroweak calculations
Journal of High Energy Physics, 2018 We present the key features relevant to the automated computation of all the leading- and next-to-leading order contributions to short-distance cross sections in a mixed-coupling expansion, with special emphasis on the first subleading NLO term in the ...

Boosting perturbative QCD stability in quarkonium production
, 2019 The aim of this paper is to introduce a general way to stabilize the perturbative QCD computations of heavy quarkonium production in the boosted or high-momentum transferring region with tree-level generators only.

Complete NLO corrections to W+W+ scattering and its irreducible background at the LHC
Journal of High Energy Physics, 2017 The process pp → μ +ν μ e+νejj receives several contributions of different orders in the strong and electroweak coupling constants. Using appropriate event selections, this process is dominated by vector-boson scattering (VBS) and has recently been ...
