Two-particle momentum correlations in jets produced in e?‘’+ e?‘’a?’ annihilation at $sqrt{s} = 60$ GeV

摘要

The goal of this analysis is to measure the two-particle momentum correlation in jets, in the reaction e?‘’+ e?‘’a?’ a?’ hadrons, to study its dependence on jet energy, and compare the results with analytical predictions of the next-to-leading log approximation (NLLA), using data collected by the AMY detector at a centre of mass energy of 60 GeV. Results are obtained for charged particles and for events with $E_{c.m.} = 60$ GeV.
