A Consistent Way of Analysis of Hadrons Measured in a Finite Rapidity Interval in Relativistic Heavy-ion Collisions

A new iteration method is proposed for analyzing both the multiplicities and the transverse momentum spectra measured only within a small rapidity interval and with low momentum limit without any inconsistency or ad hoc assumptions and applied to the hadron data by the ALICE collaboration in Pb+Pb collisions at 2.76 TeV/A. In order to correctly consider the resonance contribution only to the small rapidity interval, ratios involving only those hadrons whose transverse momentum spectrum is available are considered. In spite of the small number of ratios considered, the fittings of both the ratios the transverse momentum spectra are excellent. Also the calculated ratios involving strange baryons with parameters obtained agree with data surprisingly well.
