Bug Description
Hi Benj, Eric,
I'm investigating some issue (in MG5aMC) for the following run:
import model sm-no_b_mass
generate u b > h t d @1
output
launch
set no_parton_cut
set fixed_scale 73
Then when I looked at the plot of
sqrts I get a peak at 0!
But on the plot M(h t d), I do not see such peak. (and the same reported cross-section for both plot)
I have also run the standard test routine on the associate sample and the 4 momentum conservation was reported as ok.
Cheers,
Olivier

Hi Olivier,
This was a bug with the LHE reader. The first event was not read properly. I fixed it in v1.7beta. In the meantime, can you please try with /madanalysis. irmp.ucl. ac.be/raw- attachment/ wiki/MA5SandBox /ma5_v1. 7.13.tgz <https:/ /madanalysis. irmp.ucl. ac.be/raw- attachment/ wiki/MA5SandBox /ma5_v1. 7.13.tgz>
