Tests of a particle flow algorithm with CALICE test beam data

Understand

The studies presented in this paper provide a first experimental test of the Particle Flow Algorithm (PFA) concept using data recorded in high granularity calorimeters.

• Pairs of overlaid pion showers from CALICE 2007 test beam data are reconstructed by the PandoraPFA program developed to implement PFA for a future lepton collider.
• Recovery of a neutral hadron's energy in the vicinity of a charged hadron is studied.
• The impact of the two overlapping hadron showers on energy resolution is investigated.
