Long-range angular correlations of charged particles in high multiplicity $e^+ e^−$ collisions at 91 GeV using archived data from the ALEPH detector at LEP

The first measurements of two-particle angular correlations for charged particles emitted in $e^+ e^−$ collisions at a center-of-mass energy of 91 GeV are presented. The archived data are collected with the ALEPH detector at LEP. The correlation functions are measured over a broad range of pseudorap...

description The first measurements of two-particle angular correlations for charged particles emitted in $e^+ e^−$ collisions at a center-of-mass energy of 91 GeV are presented. The archived data are collected with the ALEPH detector at LEP. The correlation functions are measured over a broad range of pseudorapidity and azimuthal angle of the charged particles. Those results are compared to predictions from the PYTHIA event generator. In contrast to the results from high charged particle multiplicity nucleon-nucleon, nucleon-nucleus and nucleus-nucleus collisions, where long-range correlations with a large pseudorapidity gap are observed, no significant enhancement of long-range correlations is observed with respect to PYTHIA predictions, which do not include additional final state interactions of the outgoing partons.
