✦ Synopsis

Atomic number (A) and energy ( √ s) scaling exponents of multiplicity and transverse energy in heavy-ion collisions are analytically derived in the perturbative QCD + saturation model. The exponents depend on the small-x behaviour of gluon distribution functions at an x-dependent scale. The relation between initial-state and final-state saturation is also discussed.
