Abstract
At future $e^{+}e^{-}$ machines, many of the interesting physics processes result in multi-jet final states, with jets coming from either W or Z boson decay. It is therefore desired to discriminate W and Z hadronic decays, which is largely driven by the jet energy resolution. A W/Z separation of 2.3 - 2.6 $\sigma$ leads to the requirement of a jet energy resolution of 3-4% over a wide range of jet energies. This can be achieved with the Particle Flow reconstruction approach, in which the separation of charged and neutral particles is of substantial role. Highly granular calorimeters placed inside a magnetic coil is therefore desired. The CALICE collaboration has been developing various electromagnetic and hadronic calorimeter concepts to meet these requirements. As a first step, the physics prototypes were built to prove the capability to deliver the desired physics. As a next step, technological prototypes have to be built to demonstrate the feasibility of building such detectors in reality. In this talk/proceeding, we discuss briefly the results obtained with the physics prototypes, followed by the recent developments of the technological prototypes.
