Delphes/Pythia error: No file file pythia_events.hep currently available

Hi,

Looks like PY6 do not support such model.
PY6 support only slha1 type of mssm model, So I’m not too surprised by that.
They are no hope that PY6 author include such supports by now.
You then have to use another shower (outside of madgraph framework)

Cheers,

Olivier

Hi Oliver

Thank you so much. After a bit of research I found that (arXiv:1106.0522) its possible to generate Pythia8 libraries to use SLHA2 file format, so I tried to used it as shown in examples but during the compilation I had the following error:

The compilation fails with the following output message:
     g++ -c -I../include -I. Sigma_UMSSM_d1d1bar_c1c1bar.cc -o tmp/archive/Sigma_UMSSM_d1d1bar_c1c1bar.o
     Sigma_UMSSM_d1d1bar_c1c1bar.cc: In member function ‘void Pythia8::Sigma_UMSSM_d1d1bar_c1c1bar::calculate_wavefunctions(const int*, const int*)’:
     Sigma_UMSSM_d1d1bar_c1c1bar.cc:285:11: error: ‘FFV2_3P0_3’ was not declared in this scope
            w[8]);
                ^
     make: *** [tmp/archive/Sigma_UMSSM_d1d1bar_c1c1bar.o] Error 1

I saw that there has been a similar problem in here(https://bugs.launchpad.net/mg5amcnlo/+bug/1186766) which you provided the patch but since It's quite old it doesnt match with my version (2.4.2). is there any possibility to fix this?

Thank you very very much for everything.
Best regards
Jack

debug file is as follows:

Hi Jack,

the recommend way of using pythia8 is not to use the "output pythia8"
but generate lhef file and then use py8 to shower it.

I’ll check that this output mode is working again in the next version of the code.

Cheers,

Olivier
