PFClusters in full simulation

General informations

  • $\eta$ range used for barrel is $0.0<|\eta|<1.3$, for endcap $1.5<|\eta|<2.9$ and for transition between subdetectors $1.3<|\eta|<1.5$

SinglePi0Cluster

Aim of this code is to study cluster reconstruction in case of close clusters (2 seeds in same topological cluster).
  • Preselecion of event can be done according to the distance between the 2 photons at the Ecal entrance radius. A filter SinglePi0Filter can be used to do skimming based on this distance.
  • Option to look at all cases where one clusters associated for each photons or only at cases where 2 clusters are in same topological cluster
  • Code works for all kind of generated particle giving 2 secondaries ($K^0_s \rightarrow \pi^+ \pi^-$)

FakeInTopoCluster

Aim of this code is to study fake seeds in topological cluster coming from a particle with no interaction in the tracker. This fakes are visible in hadron clusters in Ecal and Hcal. Cuts on seed are possible to avoid fakes without loosing second seeds coming from close particles like in $\pi^0 \rightarrow \gamma\gamma$. Code looks at energy of seeds and energy difference with neighbours in case of 2 seeds in same topological cluster.

ClustersInEvents

This module look at clusters in any kind of events, histos are filled for Ecal and Hcal. They concern :
  • number of clusters
  • number of rechits
  • energy, $\eta$, $\phi$

CompareClusters

This module compare clusters from 2 branches from same sub-detector. The second branch comes from a new clustering with different conditions. Differences in energy and number of rechits are computed.

ReClusteringFilter

This filter select events where in 2 clusters branches, the size of the clusters matched to the generated particle are different.
