We insist on the particular interest of polarized photon-photon collisions which should allow to identify the origin of the large observable differences between various, CSM conserving or CSM violating, compositeness possibilities. %G English %L hal-01495847 %U https://hal.science/hal-01495847 %~ IN2P3 %~ CNRS %~ LUPM %~ UNIV-MONTPELLIER %~ LUPM_IFAC %~ UM-2015-2021
