Abstract
We show that recently measured transverse momentum spectra of identified particles exhibit geometrical scaling (GS) in scaling variable ÏmËT=(mËT/Q0)2(mËT/W)λ where mËT=m2+pT2âm. 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.
