摘要：
CALICE collaboration is developing highly granular calorimeters for future high energy e+e- colliders. Using Particle Flow Algorithms for individual reconstruction of particles in the jets, they provide currently the best jet energy resolution. At high jet energies (typically above 70 - 100GeV in the proposed detectors), the jet particle showers start to overlap, and the resolution is determined by the ability to separate them. Here, we present results on the separation power of: 1) two overlapping electromagnetic showers with CALICE physics prototype of silicon-tungsten electromagnetic calorimeter (SiW ECAL); 2) electromagnetic-hadronic showers with physics prototypes of SiW ECAL and analog scintillator-iron hadronic calorimeter (AHCAL). We use three available reconstruction programs and compare the results with a Monte Carlo simulation.
