Predicted galaxy clusters number counts detected from the Sunyaev-Zeldovich effect, after joint analysis of CMB, SNIa, LSS data and estimated temperature distribution function. Models describing self consistently the low and high redshift temperature distribution functions, needing non-standard evolution of T_X − M relation, lead to lower abundance of clusters, showing a deficit in the cluster number increasing with redshift (right). The best model being Ω_m = 0.317, σ₈ = 0.842, h = 0.669 and A_TM = 7.31.
