controls if a particle is treated as a resonance(lifetime=0) or a particle that has a finite lifetime.
A finite life time means it will register a geo constraint for this particle

momentum index in the statevector.
no value for beamspot as a particle
Reimplemented from ParticleBase.

project geometrical constraint
the direction of the momentum is very well known from the kinematic constraints that is why we do not extract the distance as a vector here

project mass constraint using the parameters of the daughters
be aware that the signs here are important E-|p|-m extracts a negative mass and messes with the momentum !
