Levy stable law of intermittency and multifractal spectrum in 28Si–AgBr collisions at 14.6 AGeV

The scaled factorial moments Fq are studied for 28Si–AgBr collisions at 14.6 AGeV. These moments follow the generalized power law Fq(M) ∝[g(M)] q. The values of q/ 2 obtained from the linear fits of ln Fq versus ln F2 graphs are found to obey the Brax–Peschanski formula with Levy index μ = 1.635 ± 0.012 for η space and μ = 1.801 ± 0.003 for space. These values lie within the Levy stable region 0 μ 2. An analytical continuation of the Brax–Peschanski formula has been used to obtain the multifractal spectra f(αq) in negative q region.
