Query: On the limits of the hadronic energy resolution of calorimeters   In particle physics experiments, the quality of calorimetric particle
detection is typically considerably worse for hadrons than for electromagnetic
showers. In this paper, we investigate the root causes of this problem and
evaluate two different methods that have been exploited to remedy this
situation: compensation and dual readout. It turns out that the latter approach
is more promising, as evidenced by experimental results.
