WIP: tests and fixes for EWdim6 UFO models #847

Open valassi opened 1 month ago

Hi @zeniheisser @oliviermattelaer this is a WIP PR with some tests and fixes for EWdim6 models.

In particular it adds to the git repo and adds tests for import model EWdim6; generate u d~ > w+ z which Zenny suggested in #615.

It turns out that my recent patches for SUSY, HEFT and SMEFT fixed code generation (so #615 is fixed). The code also builds and runs.

However there are some wrong results, in particular a mismatch between HRDCOD=01 and HRDCCOD=1 results (see #846). I think that HRDCOD=0 results are fine (because they give the same as fortran) but HRDCOD=1 are wrong.

Anyway, I keep this in WIP as long as that issue is not understood and fixed.
