Another parent mapping problem

Description (last modified by Frank Siegert)

I've added an - admittedly stupid - model to Sherpa, a flavour-changing Z'. Running all possible channels of t-t, tbar-tbar, t-tbar production with semileptonic decays (one top goes to leptons) produces two errors:

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. which 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.

{{{Cluster_Algorithm::Cluster(): Failed to determine configuration. Rejecting point which I do not understand at all.}}}

I find both errors kind of frightening - that's why I think it is critical that we understand what's going on. The Run.dat is attached. I've also committed the model.

The model is not on trunk, only the Makefile.am have been modified, so I can't test it yet. But there is a small typo (I assume) in YUYKAWA[5] 0.

Once the model is committed, I can look at the integration and cluster issue.

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.
