Functional reduction of Feynman integrals

open access: yesJournal 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

Constructing All-Order Corrections to Multi-Jet Rates [PDF]

open access: yes, 2009
We discuss the universal behaviour of scattering cross sections in the limit of infinite rapidity separation between all produced particles, and illustrate the behaviour explicitly for the production of n jets, W+n jets, Z+n jets for n=2,3,4, and for H+2,

Resummed photon spectrum from dark matter annihilation for intermediate and narrow energy resolution

open access: yesJournal 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

Polarized q q ¯ $$ \mathrm{q}\overline{\mathrm{q}} $$ → Z+Higgs amplitudes at two loops in QCD: the interplay between vector and axial vector form factors and a pitfall in applying a non-anticommuting γ 5

open access: yesJournal 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

open access: yesJournal 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

open access: yesJournal 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

open access: yesJournal 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

Meromorphic solutions of recurrence relations and DRA method for multicomponent master integrals

open access: yesJournal of High Energy Physics, 2018
We formulate a method to find the meromorphic solutions of higher-order recurrence relations in the form of the sum over poles with coefficients defined recursively. Several explicit examples of the application of this technique are given.
