Public release of MadGraph5 v2.0 including aMC@NLO

List below the different points which necessarily need to be adressed before the public release of MadGraph5 v2.0.

When editing the above, please try to stick to the self-explanatory conventions (Syntax, fixed numbering and placement in the right section when fixed).

Open issues

2 | O.M | Generate command autocompletion

Update the autocompletion for the loop functionalities of the generate command.

[ ? ] ?.? | Comment

4 | O.M. | Generate some html output for checking the generation of the fortran code and of the output.

[ ? ] ?.? | Comment

10 | M.Z. | Fix the STOP: momentum conservation errror from madloop

MZ: DONE (r355), it was a stupid bug inside check_poles

Fixed issues

1 | R.F | Default coupling orders at NLO

Change the default chosen coupling order configuration for processes which can have mixed order contributions at LO already. Typically, one wants p p > t t~ [QCD] to return only contributions with QED = 0.

[ Fixed ] V.H. | Now in the case proposed above, it will inform the user that the configuration (QED=0,QCD=*) is chosen and warns that additional contributions of configuration (QED=2,QCD=*) are detected but discarded.

3 | V.H | Tracking of unstable points in MadFKS

For now simply from the IR cancellation test. At the end of a run, it should give their number versus the total number of calls to the virtual as well as writing out the first ten (with the renormalization scale used) in a log file like 'UPS.log' in the G* folder.

MZ: DONE

5 | O.M. | Have a nice error/treatment if fast jet is missing

MZ: DONE (r341)

6 | O.M. | Explaining how to launch the shower (and the point for the counter-term in the tutorial

MZ: DONE (r343)

7 | O.M. | add process crash in MC@NLO (if no generate are done before)

MZ: DONE (r341)

8 | M.Z. | param_card updates do not affect results

MZ: DONE (r352), was only related to tests

Development issues and strategies

The "end" of version 4, the early "beginning" of version 5

When do we freeze MG/ME v4? 1st October 2009, right after MG meeting

What do we include in the frozen v4?

1. lhapdf will be in.
2. proto CKKW matching. Only initial state are in. Final state will be there.
3. FR models + USRMOD2 will be in. Old models will be moved in a subdir of Models/ called Legacy/ + give the possibility to use old param_card.dat ? An email to the whole team to fix details.

What kind of modification will be allowed ?

1. Any new model (FR compatible)
2. Any other modification can be released as downloadable patches to "protect" the code.

MG@NLO stuff will be developed on top of the frozen in v4 and added to v5 when ready.

MG4Pythia: considered as a side project anyway, especially if the only public thing to release is a 2>2 process library, not the code to produce it (which is much more v5 in the philosophy). Johan will be in charge for the wrapping script, Tim will help for possible modifications to MG or HELAS required to produce off shell final state particles.

This is the official list of proposed improvements/developments. Some of them are prioritized.
