e+ e- > b b~ problems

Asked by Jilberto Zamora-Saa on 2020-01-31

I'm trying to simulate the collision e+ e- > b b~ at Belle II energies 7 and 4 GeV. However, the simulation work fine at symmetrical energies 7 and 7 GeV, 5.5 and 5.5 GeV and so on... but when I run 7 and 4 GeV madgraph works fine and Pythia8 output file is empty.

There is someone, who experienced this kind of problem, that could help me?

thanks in advance,
Jilberto

Hi,

What is the content of the py8 log?
Just to check what he is crashing/complaining about (it is likely that I would need to tell you to contact PY8 author actually)

Cheers,

Olivier
