Python version supported are Python2.7 and Python 3.7 (or higher).<br/>
The latest version with support of Python2.6 was MG5aMC version 2.7.3 and the beta version 3.0.3.<br/>
Support for Python2.7 is still planned up to december 2021 but some new features will only be python3 compatible before that.</p>MadGraph5_aMC@NLO version 3 in beta2018-05-07T16:34:20.295269+00:002018-05-07T16:34:20.193623+00:00tag:launchpad.net,2018-05-07:/+announcement/14979Olivier Mattelaerhttps://launchpad.net/~olivier-mattelaer<p>The first version of the 3.Y series has been released today, in a beta format. This is the first MadGraph5_aMC@NLO code able to<br/>
deal with mixed-coupling expansions. In particular, this allows one to carry out QCD+EW NLO computations in the SM. This version<br/>
is restricted to fixed-order calculations.</p>Official Release of MadGraph5_aMC@NLO2013-12-16T12:48:56.123048+00:002013-12-16T12:48:55.261157+00:00tag:launchpad.net,2013-12-16:/+announcement/12270Olivier Mattelaerhttps://launchpad.net/~olivier-mattelaer<p>we would like to announce the public release of the new code</p>
<p>MadGraph5_aMC@NLO</p>
<p>now available for download at <a href="https://launchpad.net/madgraph5" rel="nofollow">https:/<wbr/>/launchpad.<wbr/>net/madgraph5</a> .</p>
<p>The new code supersedes both beta versions of aMC@NLO available since Nov 2012 and<br/>
the MadGraph5 1.5.x versions, thus unifying the two main lines of development of the LO and<br/>
NLO features in a single integrated framework.</p>
<p>The main features of the new code are:</p>
<p>0. All the tree-level/LO functionalities in the SM and BSM of MadGraph5.<br/>
1. Fully automatic computation of QCD corrections in QCD at the NLO (loop, real, counterterms) for any SM process.<br/>
2. Fully automatic event generation at the NLO, matched to Pythia8, Herwig++, Herwig6, Pythia6(Q2), Pythia6(pt, ISR only) according to the MC@NLO formalism.<br/>
3. Very significant improvements in speed and efficiency wrt the beta version of aMC@NLO, leading basically to the possibility of computing at NLO in QCD any SM process up to 2-> 4 at the Born level.<br/>
4. Automatic computation of scale and pdf uncertainties at NLO and MC@NLO level at no extra computational cost.<br/>
5. Support of the LHE format v3.0 with reweighting information for uncertainties as well as for parameter scanning.<br/>
6. A much more flexible and complete user interface, including an easy-to-use analysis framework for fixed-order NLO computations.<br/>
7. Semi-automation of the FxFx multi-parton merging at NLO with HERWIG6.</p>
<p>More details will be given in a forthcoming publication foreseen for beginning of next year.</p>aMC@NLO in MadGraph52012-11-08T20:42:17.396006+00:002012-11-08T20:07:01.121239+00:00tag:launchpad.net,2012-11-08:/+announcement/10820Olivier Mattelaerhttps://launchpad.net/~olivier-mattelaer<p>On Nov 8th 2012, version 2.0 beta of MadGraph5 has been released.<br/>
This is a major upgrade, since it includes all the features of<br/>
the aMC@NLO package, that gives the user the possibility of computing<br/>
in a fully automated manner the cross section for any Standard Model<br/>
process at the next-to-leading order in perturbative QCD, with or<br/>
without the matching to a parton shower event generator</p>
