Weirdness when {{{tex_name}}} and {{{anti_tex}}} are the same

[Christian Speckner]

I stumbled over this one when debugging the FR interface: in the situation described above, WHIZARD uses the same identifier both for particle and antiparticle when calling O'Mega. I've already briefly skimmed the code, but couldn't find the culprit.

CS, could you please give us a little more information.... What exactly goes wrong!?

[Christian Speckner]

JR, don't bother, I just tried to construct a simple testcase to reproduce this, and failed. What happened basically was that in my FeynRules? generated MSSM model file the two definitions

particle wp_sl3_plus 1000015
spin 0
name "sl3+"
tex_name "sl3+"
anti "sl3-"
anti_tex "sl3-"
mass Msl3
width Wsl3

and

particle wp_sl3_plus 1000015
spin 0
name "sl3+"
tex_name "sl3+"
anti "sl3-"
anti_tex "sl3+"
mass Msl3
width Wsl3

trigger different behavior, the lower leading to an invalid call to O'Mega ("sl3- sl3-" instead of "sl3+ sl3-" as defined in the input file). I'll assign this to myself and try to troubleshoot it as I find time, but seeing that the issue is hard to reproduce, this certainly is no showstopper.

As CS said that he really cannot reproduce this error, I close this ticket.
