We make illustrations of the ratios of new cross sections over standard ones. Specific energy dependences appear for each assumption about $b_L$, $b_R$, $t_L$, $t_R$ compositeness and CSM constraints concerning the Higgs sector. %G English %L hal-01633455 %U https://hal.science/hal-01633455 %~ IN2P3 %~ CNRS %~ LUPM %~ UNIV-MONTPELLIER %~ LUPM_IFAC %~ UM-2015-2021
