Abstract
We show that recently measured transverse momentum spectra of identified particles exhibit geometrical scaling (GS) in scaling variable τm˜T=(m˜T/Q0)2(m˜T/W)λ where m˜T=m2+pT2−m. We explore consequences of GS and show that both mid rapidity multiplicity and mean transverse momenta grow as powers of scattering energy. Furthermore, assuming Tsallis-like parametrization of the spectra we calculate the coefficients of this growth. We also show that Tsallis temperature is related to the average saturation scale.
