Bug Description

Dear developers,

I´m facing a problem while generating p p > e- e+ mu- vm~ j j QED<=4 (QCD contribution). When I'm trying to reweight these events with this process p p > e- e+ mu- vm~ j j QCD=0 QED<=6 (pure electroweak) the error is this one:

INFO: starts to compute weight for events with the following modification to the param_card:
INFO: set param_card anoinputs 4 1e-12 # orig: 0.0
KEEP:
INFO: Event nb 0 current time: 12h40
Command "reweight Events/run_01/unweighted_events.lhe" interrupted with error:
KeyError : ((1, 21), (-14, -11, 2, 11, 13, 21))

and the reweighting card is this:

change process p p > e+ e- mu- vm~ j j QCD=0 QED<=6
change helicity False
launch --rwgt_name=SM
/afs/cern.ch/work/e/ekasimi/decomposition/full_decomposition/cards/param_card_SM.dat

Is there any way to do the reweighting?

Thanks in advance,
Eirini

Hi,

This actually makes a lot sense since you do not have gluon final state for you re-weighting definition. So indeed you do not have any matrix-element with which to re-weight and therefore this lead to a crash.

Now I guess that in this particular case, the correct behavior is to set the weight of all those events to zero. I do not want to have this as the default behavior since this is the sign of a bug in 99% of the case. So I will add a flag in 2.6.7 in order to allow to set the weight to 0.

the way to set the flag would be
change allow_missing_finalstate True

Cheers,

Olivier
