[ 1 ] - توزیع چندگانگی ذرات باردار در نابودی +e-e در انرژی مرکز جرم GeV54-57 و مقیاس KNO
In this paper, we investigate the multiplicity of charged particles in e+ e– annihilation by using different models. To achieve this we first fit the multiplicity distribution of charged particles in the energy range of 54-57 GeV by using both the Poisson distribution and KNO scaling, then we compare these results with multiplicity distribution at the lower energies. This comparison shows that...
[ 2 ] - بررسی رویدادهای چند جتی در نابودی الکترون - پوزیترون
Analysis of electron – positron annihilation into hadrons in the range of energies above 60 GeV shows that apart from two jet events, there are evidence for three jet events that according to the QCD theory interpreted as a gluon radiation by a quark. However, the higher order diagrams lead to four jet events. In this paper, we study the fragmentation of quarks and gluons into hadronic jets . ...
