Double-real-virtual and double-virtual-real corrections to the three-loop thrust soft function

open access: yesJournal of High Energy Physics, 2022
We compute the O $$ \mathcal{O} $$ ( α s 3 $$ {\alpha}_s^3 $$ ) double-real-virtual (RRV) and double-virtual-real (VVR) soft contributions to the thrust/zero-jettiness event shape.

A Feynman integral depending on two elliptic curves

open access: yesJournal of High Energy Physics, 2022
We study a two-loop four-point function with one internal mass. This Feynman integral is one of the simplest Feynman integrals depending on two elliptic curves. We transform the associated differential equation into an ε-form. We study the entries of the

Generalized Parton Distributions -- theoretical review --

open access: yes, 2005
In this talk an introduction to generalized parton distributions is given. Recent developments are shortly reviewed, including non-perturbative calculations, phenomenological aspects and evaluation of higher order perturbative and power corrections ...

Baikov representations, intersection theory, and canonical Feynman integrals

open access: yesJournal of High Energy Physics, 2022
The method of canonical differential equations is an important tool in the calculation of Feynman integrals in quantum field theories. It has been realized that the canonical bases are closely related to d-dimensional d log-form integrands. In this work,

Jet Production at HERA

open access: yes, 2001
I review the status of perturbative QCD calculations for jet production in eP-scattering at HERA. I will discuss possibilities of combining fixed order, especially higher order, calculations and parton showers.Comment: 13 pages, 5 eps ...

Higgs-boson production through gluon fusion at NNLO QCD with parton showers

open access: yes, 2014
We discuss how the UN2LOPS scheme for matching NNLO calculations to parton showers can be applied to processes with large higher-order perturbative QCD corrections. We focus on Higgs-boson production through gluon fusion as an example. We also present an

Deviation pattern approach for optimizing perturbative terms of QCD renormalization group invariant observables [PDF]

open access: yes, 2017
We first consider the idea of renormalization group-induced estimates, in the context of optimization procedures, for the Brodsky-Lepage-Mackenzie approach to generate higher-order contributions to QCD perturbative series.

Next-to-leading order electroweak corrections to gg → HH and gg → gH in the large-m t limit

open access: yesJournal of High Energy Physics, 2023
We compute two-loop electroweak corrections to Higgs boson pair and Higgs plus jet production, taking into account all sectors of the Standard Model. All diagrams with virtual top quarks are computed in an expansion for large top quark mass up to order 1/

NLO EW and QCD corrections to polarised same-sign WW scattering at the LHC

open access: yesJournal of High Energy Physics
We present the first calculation of same-sign WW scattering at the LHC in the fully leptonic decay channel including the modelling of polarisation for intermediate electroweak bosons and radiative corrections up to NLO EW+QCD accuracy.

Master integrals for O $$ \mathcal{O} $$ (αα s ) corrections to H → ZZ *

open access: yesJournal of High Energy Physics, 2022
We present analytic results for all the Feynman integrals relevant for O $$ \mathcal{O} $$ (αα s ) virtual corrections to H → ZZ * decay. We use the method of differential equations to solve the master integrals while keeping the full dependence on the ...
