accumulate() [1/2]

void CaloTruthAccumulator::accumulate ( const edm::Event &  event, const edm::EventSetup &  setup  )

overrideprivatevirtual

Create handle to edm::HepMCProduct here because event.getByLabel with edm::HepMCProduct only works for edm::Event but not for PileUpEventPrincipal; PileUpEventPrincipal::getByLabel tries to call T::value_type and T::iterator (where T is the type of the object one wants to get a handle to) which is only implemented for container-like objects like std::vector but not for edm::HepMCProduct!

accumulateEvent()

template<class T >

void CaloTruthAccumulator::accumulateEvent ( const T &  event, const edm::EventSetup &  setup, const edm::Handle< edm::HepMCProduct > &  hepMCproduct  )

private

Both forms of accumulate() delegate to this templated method.

Build the main decay graph and assign the SimTrack to each edge. The graph built here will only contain the particles that have a decay vertex associated to them. In order to recover also the particles that will not decay, we need to keep track of the SimTrack used here and add, a-posteriori, the ones not used, associating a ghost vertex (starting from the highest simulated vertex number), in order to build the edge and identify them immediately as stable (i.e. not decayed).

To take into account the multi-bremsstrahlung effects in which a single particle is emitting photons in different vertices keeping the same track index, we also collapsed those vertices into 1 unique vertex. The other approach of fully representing the decay chain keeping the same track index would have the problem of over-counting the contributions of that track, especially in terms of hits.

The 2 auxiliary vectors are structured as follow:

1. used_sim_tracks is a vector that has the same size as the overall number of simulated tracks. The associated integer is the vertexId of the decaying vertex for that track.
2. collapsed_vertices is a vector that has the same size as the overall number of simulated vertices. The vector's index is the vertexId itself, the associated value is the vertexId of the vertex on which this should collapse.
