Sugano, K

The intermittency and fractal behavior in e{sup +}e{sup {minus}} annihilations has been studied using the HRS detector at PEP ({radical}s = 29 GeV). The factorial moments F{sub i}(i = 2 {approximately} 5) in small rapidity intervals show stronger intermittency slopes than those for the {pi}p, {bar p}p, and AA reactions. This direct measurement confirms our previous data derived from the k-values in the negative binomial fits to the multiplicity distributions in various central rapidity windows. The fractal moments G{sub q} have been measured for the first time in e{sup +}e{sup {minus}} annihilations. The Legendre transform f({alpha}) derived from the fractal moments show a self-similar behavior which is consistent with the jet cascading mechanism. 95 refs., 46 figs., 2 tabs.
