Abstract: (Elsevier)

In this Letter the degrees of nonextensivity of the hadronic quantum scattering systems is investigated by using Tsallis-like scattering entropies S J ( p ) and S θ ( q ), p , q ∈ R . Then, evidences for strong nonextensive statistical effects, with nonextensivity indices 1/2⩽ p ⩽0.6, as well as, for the (1/2 p +1/2 q =1)- nonextensivity conjugation , are obtained by fitting the pion–nucleus experimental entropies with the PMD - SQS - optimal state predictions. The interpretation of these strong nonextensive statistical effects as indirect manifestations of the presence of the quarks and gluons in the hadronic quantum system is suggested.
