Hi Tobias,
could you please provide the SINDARIN file? The HiggsSingletUFO file is at the UFO page?
Cheers,
    JRR

[Tobias Striegl (stto)]

Hello,

the UFO files are generated by FeynRules. I have attached the whole output here.

The Sindarin file is only the small testing example at the bug report page.

Regards,
Tobias Striegl.

Oops, sorry, the SINDARIN is indeed at the beginning, overlooked it. But I needed the UFO model to reproduce it. This is actual not a valid UFO model, as in the expressions of the values in couplings.py there still appear python expressions like cmath.sqrt etc. and on the other hand things like \[Theta] which look like ASCII transcriptions of Mathematica code. These actually lead to the error message
Fatal error: exception Failure("invalid character at `\\'")
| command: /home/reuter/local/bin/omega_UFO.opt -model:UFO_dir ./HiggsSinguletUFO -model:exec -model:write_WHIZARD > HiggsSinguletUFO.ufo.

So it seems that your UFO file is broken.

[Thorsten Ohl (thomega)]

I will add code handling the Mathematica \[...] strings or add least provide better error messages.

[Thorsten Ohl (thomega)]

I have added code handling Mathematica symbols like "\[Rho]1".

Unfortunateley, the UFO files contain another, more serious, error: several couplings refer to a parameter "z" which is never declared. Currently, this is is only detected by the Fortran compiler, but I can add diagnostics for this. However, I am reluctant to add heuristics that will automagically introduce missing parameters. The UFO files should be correct.
