Comment:

I can not reproduce the first error.

The second error is related to r17279 and bug report (#159) which I hope Stefan will be able to attend to when he comes back. I'll add a comment there about this example here (which is simpler than the test case in #159).

Thus closing, please re-open if the first error is reproducable after all.

  • Ticket #161 – Description

    initial v2  
    11I've added an - admittedly stupid - model to Sherpa, a flavour-changing Z'. 
    22Running all possible channels of t-t, tbar-tbar, t-tbar production with semileptonic decays (one top goes to leptons) produces two errors:
    3 1. Process_Integrator::Sigma2(): Inconsistent summation for '2_6__d__db__t[nu_mu__mu+__b]__tb[s__cb__bb]' \in '2_6__j__j__t[nu_mu__mu+__b]__tb[j__j__bb]', m_sn = 0 vs. p->m_sn = 10366.

    46which has to do with the mapping on parent processes - this process seems not to integrate.  Funnily enough, it seems as if the one with the t going to jets and the tbar to muons would work out.

    7 which I do not understand at all.

    912I find both errors kind of frightening - that's why I think it is critical that we understand what's going on.
