【 摘 要 】

A self-affne analysis of charged-particle multiplicity distribution (protons + pions) in 𝜋− –AgBr interaction at 350 GeV/c is performed according to the two-dimensional factorial moment methodology using the concept of Hurst exponent in $X_{cosheta^{-}}$ 𝑋𝜙 phase space. Comparing with the results obtained from self-similar analysis, the self affine analysis shows a better power-law behaviour. Corresponding results are compared with shower multiplicity distribution (pions). Multifractal behaviour is observed for both types of distributions.
