%description
MadGraph5_aMC@NLO is a framework that aims at providing all the elements 
necessary for SM and BSM phenomenology, such as the computations of 
cross sections, the generation of hard events and their matching with 
event generators, and the use of a variety of tools relevant to event 
manipulation and analysis. Processes can be simulated to LO accuracy 
for any user-defined Lagrangian, and the NLO accuracy in the case of 
QCD corrections to SM processes. Matrix elements at the tree- and 
one-loop-level can also be obtained.
MadGraph5_aMC@NLO is the new version of both MadGraph5 and aMC@NLO that 
unifies the LO and NLO lines of development of automated tools within 
the MadGraph family. It therefore supersedes all the MadGraph5 1.5.x 
versions and all the beta versions of aMC@NLO.
The standard reference for the use of the code is: J. Alwall et al, 
"The automated computation of tree-level and next-to-leading order 
differential cross sections, and their matching to parton shower 
simulations", arXiv:1405.0301 [hep-ph]. A more complete list of
