Two-particle Correlation and Jet measurements in \(e^{+}e^{-}\) Collisions at 91 GeV with Archived ALEPH Data

The first measurement of anti-kT jets and two-particle angular correlations of charged particles emitted in high energy e+e− annihilation is presented. The archived data at a center-of-mass energy of 91 GeV were collected with the ALEPH detector at LEP between 1992 and 1994. At 91GeV, no significant...

description The first measurement of anti-kT jets and two-particle angular correlations of charged particles emitted in high energy e+e− annihilation is presented. The archived data at a center-of-mass energy of 91 GeV were collected with the ALEPH detector at LEP between 1992 and 1994. At 91GeV, no significant long-range correlation was observed in either the laboratory coordinate analysis or the thrust coordinate analysis, where the latter is sensitive to a medium expanding transverse to the color string between the outgoing q¯q pair from Z boson decays. We also present the first measurement of anti-kT jet energy spectra and substructures compared to various event generators, NLO, and NLL’+R resummation calculations.
