New Progress in the Study of High Energy Non-Linear Phenomena

Classical Chromodynamics has chaos solution. But quantum chaos is a verydifficult theoretical problem. Therefore, at present the non-linear study in high energyPhysics can only be carried on using phenomenological methods. By the end ofeighties, large local fluctuations were observed in experiments, which shmulatedextensive study on high energy non-linear phenomena- intermittency and fractal. Itwas observed experimentally that l-dimensional factorial moments tend to saturate.This was explained as the result of projechon of higher-dimensional intermittency intolower dimension. However, even in 3-dimension the factorial moments do not obey astrict scaling law. ms difficulty has brought the study to a standstill. Later, it wasrecognized that the reason lies in the fact that the phase space of high energymultiparticle final states is highly anisotuopy and therefore the corresponding fractal isself-affine. The anomalous scaling can be observed when and only when the phasespace is divided in a correct anisotropical way. Thi predichon has been verified inthe experimental data from NA22 and NA27. The anomalous scaling in theseexperiments has been observed successfully, making a breakthrough in high energynon-linear study. This progress is reviewed in mis paper together with some commentsand discussions.
