6.8 Conclusions
During the past 40 years calorimetry has matured into a precision measurement
technique, indispensable to modern particle physics experiments. The Higgs boson,
cornerstone of our present understanding of matter, owes its discovery to calorimetry.
Understanding and modelling the physics processes at work in calorimetry at the
1% level has been achieved. Based on this understanding and helped by modern
signal processing techniques, developments aim at characterizing the individual
showers, at optimizing further particle identification and at reaching the intrinsic
performance level for jet spectroscopy, needed for the next generation of precision
and discovery experiments.
Acknowledgments We thank many colleagues for discussions and T. Carli for a careful reading
of the manuscript.
