Abstract
The calculation of inclusive spectra of pions produced in pp and AA collisions as functions of the rapidity y is presented within the self-similarity approach. It is shown that at not too large rapidities y one can obtain an analytical form of the self-similarity function \(\varPi (y,p_t)\) dependent on y and on the hadron transverse momentum \(p_t\). A satisfactory description of the data on rapidity spectra at \(|y|\le \) 0.3 is presented within the approach applied. The energy dependence of these spectra is also shown to be universal.
