| Abstract: | First, 5 millions p(?) collision events are produced at CERN-Sp(?)S collider and the jets in events arc identified by the"Cone algorithm". Then,the properties of the jets,such as the percentags of different jet numbers, cumulant variables, the distributions of particle numbers according to the regions of y,Pt,(?) and the saturated curves of 1-dimensional second-order factorial moments, etc, are studied. Finally, the anomalous scaling property of 3-dimensional second-order factorial moments is obtained from self-affine analysis. |
