Abstract：
A self-affine analysis is performed on the jets (minijets) produced in proton-antiproton collisions at CERN SpS collider energy. The jets are identified by the "Cone algorithm". The Hurst exponents are obtained through the study on the 1-D factorial moments. A 3-D self affine analysis is performed according to these Hurst exponents. The results provide further evidence that ,the dynamical fluctuations inside jets are anisotropic in the longitudinal-transverse planes and isotropic in the transverse plane, which mimics the dynamical fluctuations in SPS fixed-target hadron-hadron collisions.
