摘　　要：Nonextensive statistics in a blast-wave model is implemented to describe the identified hadron production in relativistic p+p and nucleus-nucleus collisions.Incorporating the core and corona components within the TBW formalism allows us to describe simultaneously some of the major observations in hadronic observables at the Relativistic Heavy-Ion Collider(RHIC):the amount of constituent quark scaling(NCQ),the large radial and elliptic flow,the effect of gluon saturation,and the suppression of hadron production at high transverse momentum(p_(T))due to jet quenching.In this formalism,the NCQ scaling at the RHIC appears as a consequence of a non-equilibrium process.Our study also provides concise reference distributions with a leastχ^(2) fit of the available experimental data for future experiments and models.
