Primary focus of the calorimetric R&D effort is the Particle Flow Algorithm. This is a technique promising an excellent jet energy resolution by combining the measuring power of tracking systems, electromagnetic calorimetry and hadron calorimetry. Its application requires a method of separation of energy depositions of neutral hadrons (other than pi-zeros) from those of charged particles and photons.
