RD : Particle combiner for 5 body decays
More than an issue, this is a way to keep track and understand the default approach to use in lines for
B -> K Pi Pi (ll)
or tau->5 mu
.
one might hope to be able to use a 5Body ParticleCombiner which seems to be not declared in https://gitlab.cern.ch/lhcb/Phys/-/blob/master/Phys/ParticleCombiners/src/ParticleCombiner.cpp.
Is it planned to be included? If not it might be good to have a standard approach to circumvent it when a 5 body combination is needed. E.g from what i understood one has to pass by a 3+2 combination, but for special cases with same particles one might need to find also a way to get rid of combinations with clones.
What is the approach suggested to follow in this case? example : tau -> mu+ mu+ mu+ mu- mu-, to prevent the 3body container and 2 body container to combine in a way to avoid duplicates being used, is the suggestion to do 3mu+ combination and 2mu- for example?
