Import New Model

Hi Joydeep,

It looks like that FFS4 is not a valid lorentz structure.
If this is indeed set as ProjM(-1,1) this is indeed not correct.

How did you set this lorentz structure? Did you use FR?

Cheers,

Olivier

Hi Olivier,

Hi JoyDeep,

Since this looks like a FR problem, I'm pointing this problem to FR author.
Could you send to the following list of email (they are in cc for this email)
olivier.mattelaer__AT__uclouvain.be
duhrc__AT__itp.phys.ethz.ch
fuks__AT__cern.ch
cdegrand__AT__illinois.edu

1) your FR file
2) the resulting UFO model,

Cheers,

Olivier
