Dear ROOTers,

I'm trying run pythia using the TPythia6.

The following initialization:
TPythia6* pythia = new TPythia6;
pythia->Initialize("fixt", "gamma/e-", "p+", 5.); was recognized by older versions of ROOT but now I'm trying to use it with the ROOT version 5.18/00 it gives the following error message:

1****************** PYINIT: initialization of PYTHIA routines
*****************

 Error: unrecognized beam particle 'gamma/e-fixt'D0  Execution stopped!

I would appreciate very much any help or advise.

With best regards,
Hayk. Received on Fri Jul 24 2009 - 15:41:09 CEST
