QUARK PRODUCTION RULE IN e+e→TWO JETS EVENTS AT HIGH ENERGY

  • By Using the advantage that, in e+e→heavy quark jets, quarks excited by electromagnetic interaction and that by strong interaction can be distinguished from each other, the production rule for the later is investigated. It is found that the number of the quark produced satisfies a simple universal rule, and the resulted , i> multiplicity distribution and forward-backwark correlation etc are all in agreement with experiment. The comparison of with the data is presented.

QUARK PRODUCTION RULE IN e+e→TWO JETS EVENTS AT HIGH ENERGY

    Corresponding author: XIE Qu-Bing,

Abstract: By Using the advantage that, in e+e→heavy quark jets, quarks excited by electromagnetic interaction and that by strong interaction can be distinguished from each other, the production rule for the later is investigated. It is found that the number of the quark produced satisfies a simple universal rule, and the resulted , i> multiplicity distribution and forward-backwark correlation etc are all in agreement with experiment. The comparison of with the data is presented.
