Query: A Monte Carlo Study on the Dynamical Fluctuations Inside Quark and
  Antiquark Jets   The dynamical fluctuations inside the quark and antiquark jets are studied
using Monte Carlo method. Quark and antiquark jets are identified from the
2-jet events in e+e- collisions at 91.2 GeV by checking them at parton level.
It is found that transition point exists inside both of these two kinds of
jets. At this point the jets are circular in the transverse plane with respect
to the property of dynamical fluctuations. The results are consistent with the
fact that the third jet (gluon jet) was historically first discovered in e+e-
collisions in the energy region 17-30 GeV.
