Two-particle momentum correlations in jets produced in e + e − annihilation at $boldsymbol{sqrt s = 60}$ GeV

摘要

The goal of this analysis is to measure the two-particle momentum correlation in jets, in the reaction e + e − → 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.
