lp:~maddevelopers/mg5amcnlo/GGVV_plugin
This plugin allows you to automatically generate the 2-loop matrix element (based on Andreas Van Manteuffel GGVVamp HepForge release) for any process of the type:
g g > V1* V2* > {X}
where V1* V2* are any SM electroweak boson, and {X} any of their decay products (even hadronic in principle). All interferences are included too and CKM matrix is arbitrary.

1. Fixed the subtraction of the I operator.
2. Rendered absolute the path of the GGVVV model automatically loaded. - 5. By Valentin Hirschi on 2017-12-28
-
1. Very small fix, adding 'REDUCTIONCODEINIT' to the list of common block veto name not to further prefix, so that all MadLoop's libraries will share the same reduction tool initializer boolean flag, hence insuring that these reduction tool only ever get initialized once.
- 4. By Valentin Hirschi on 2017-12-23
-
1. Changed LHAID of ResidueToReturn to 4004
2. Fixed last remaining bug in the re-instatement of scale dependency in GGVVAmp. Cross-checked against g g > h @NLOQCD in HEFT. - 3. By Valentin Hirschi on 2017-12-22
-
1. Added the possibility of returning poles from GGVV output (see param ResidueReturned in param_card).
2. Fixed the mu_r dependence and the finite part of the 2-loop result. - 2. By Valentin Hirschi on 2017-12-20
-
1. Added necessary post-processesing of the file processes_
meta_informatio n to include prefixes and n_loops. - 1. By Valentin Hirschi on 2017-11-09
-
1. First version of the GGVV amp plugin for MG5aMC which can in principle
automatically generate the 2-loop X 1-loop amplitude for any process
G G > V^* V^*, with arbitrary decays of the SM V-boson, including
all interferences between the various V assignments.
It was tested to the extend that it can reproduce the 1-loop x 1-loop
result from MadLoop Standalone.
