Journal of High Energy Physics, 2017 We compute the two-loop master integrals required for the leading QCD corrections to the interaction vertex of a massive neutral boson X 0, e.g. H, Z or γ∗, with a pair of W bosons, mediated by a SU(2) L quark doublet composed of one massive and one ...

Functional reduction of Feynman integrals
Journal of High Energy Physics, 2019 A method for reducing Feynman integrals, depending on several kinematic variables and masses, to a combination of integrals with fewer variables is proposed. The method is based on iterative application of functional equations proposed by the author. The

Relic density computations at NLO: infrared finiteness and thermal correction [PDF]
Journal of High Energy Physics, 2014 Abstract There is an increasing interest in accurate dark matter relic density predictions, which requires next-to-leading order (NLO) calculations. The method applied up to now uses zero-temperature NLO calculations of annihilation cross sections in the standard Boltzmann equation for freeze-out, and is conceptually ...

Optics Express, 2022 Non-line-of-sight (NLOS) imaging of hidden objects is a challenging yet vital task, facilitating important applications such as rescue operations, medical imaging, and autonomous driving. In this paper, we attempt to develop a computational steady-state NLOS localization framework that works accurately and robustly under various illumination conditions.

Resummed photon spectrum from dark matter annihilation for intermediate and narrow energy resolution
Journal of High Energy Physics, 2019 The annihilation cross section of weakly interacting TeV scale dark matter particles χ 0 into photons is affected by large quantum corrections due to electroweak Sudakov logarithms and the Sommerfeld effect. We extend our previous work on the resummation

Journal of High Energy Physics, 2020 We consider QCD corrections to two loops for the polarized amplitudes of q q ¯ $$ q\overline{q} $$ → Z + Higgs boson. First we show how the polarized amplitudes of b b ¯ $$ b\overline{b} $$ → Zh associated with a non-vanishing b-quark Yukawa coupling and

Precise yield of high-energy photons from Higgsino dark matter annihilation
Journal of High Energy Physics, 2020 The impact of electroweak Sudakov logarithms on the endpoint of the photon spectrum for wino dark matter annihilation was studied intensively over the last several years. In this work, we extend these results to Higgsino dark matter χ 1 0 $$ {\chi}_1^0 $$

Virtual corrections to gg → ZH via a transverse momentum expansion
Journal of High Energy Physics, 2021 We compute the next-to-leading virtual QCD corrections to the partonic cross section of the production of a Higgs boson in association with a Z boson in gluon fusion.

Electroweak corrections to diphoton plus jets
Journal of High Energy Physics, 2017 We calculate the next-to-leading order electroweak corrections to the production of a photon pair in association with zero, one and two jets at the LHC. We use GoSam and Sherpa to obtain the results in a fully automated way. For a typical set of fiducial

NLO computation of diffractive di-hadron production in a saturation framework
Journal of High Energy Physics, 2023 Abstract The cross-sections of diffractive double hadron photo- or electroproduction with large pT, on a nucleon or a nucleus, are calculated to NLO accuracy. A hybrid formalism mixing collinear factorization and high energy small-x factorization, more precisely the shockwave formalism for the latter, is used to derive the results.
