Based on the OPP technique and the HELAC framework, HELAC-1LOOP is a program that
is capable of numerically evaluating QCD virtual corrections to scattering amplitudes. A …

… In this contribution we review the main features of the HELAC-NLO system for NLO QCD
calculations. As a case study, NLO QCD corrections for tt+ 2 jet production at LHC are illustrated …

… In this contribution we describe the main features of the HELAC-NLO approach to NLO
calculations. We provide an overview of the framework and briefly summarize a few results of …

… In this proceedings contribution, we present the results obtained with the help of the
Helac-NLO system. This software consists of the following: Helac-Phegas [1], Helac-1Loop [2], …

We present NLOAccess, an online platform acting as a virtual access to automated
perturbative computations of physical observables related to collider physics within collinear …

… In this framework matrix elements obtained from the HELAC-NLO package are used to
provide predictions of distributions at the hadron level that are correct up to next-to-leading order …

… Interfacing NLO calculations, as structured in HELAC-NLO, with PS and hadronization effects,
within the POWHEG framework, open the exciting possibility of realistic, precise and reli…

… The program HELAC-NLO is presented, which enables automated calculations for hard
scattering processes at next-to-leading order QCD. In particular an update of ONELOOP, used …

Despite the up to now successful interpretation of the experimental data collected at the
Large Hadron Collider (LHC) and the breakthrough discovery of the Higgs boson at LHC, the …

… We mention here only the HELAC-NLO framework [1], that will be used in our studies. The
software has recently been used to calculate NLO QCD corrections to a process with five …
