launch ends with non zero status: 134

[Aysuhan]

Hi everyone,

We are using MG5_aMC_v2_7_3 and trying to generate zp > t t~ decay process in 3-3-1 model (a minimal extension of the SM) using 331_-1_LO_UFO file.

While we were launching we encountered the error. The launch ends with non zero status:134 : stop all computation.

We chose the zprime mass value is 5000 TeV. (The only change we made on paramcard.dat)

This is a pythia8 error.
Since you are using an outdated version of MG5aMC, I will not able to provide you any help on such interface to pythia8.

My advice here is to run pythia8 outside of MG5aMC, (especially since such interface is designed for 2>2 collision and that it is not even clear to me how to setup pythia8 in single particle decay mode, even this is likely possible if you know the correct py8 options).

Cheers,

Olivier
