Two-photon exchange model for production of neutral vector meson pairs in e+e− annihilation

A vector-dominance two-photon exchange model is proposed to explain the recently observed production of ρρ and ρφ pairs in e+e− annihilation at 10.58 GeV with the BaBar detector. All the observed features of the data —angular and decay distributions, rates— are in agreement with the model. Predictions are made for yet-unobserved final states.

Electroweak Corrections to Four-Fermion Production in ee Annihilation

The recently completed calculation of the full electroweak O(α) corrections to the charged-current four-fermion production processes ee → ντ τμν̄μ, ud̄μ−ν̄μ, and ud̄sc̄ is briefly reviewed. The calculation is performed using complex gauge-boson masses, supplemented by complex couplings to restore gauge invariance. The evaluation of the occurring one-loop tensor integrals, which include 5and 6-point ...

Secondary Heavy Quark Pair Production in ee Annihilation

The multiplicity of heavy quarks from gluon splitting in ee annihilation has now been theoretically calculated and experimentally measured at LEP. However, the experimental measurement requires theoretical input for the shape of the multiplicity with respect to an event shape. In this paper we calculate the multiplicity of heavy quarks from gluon splitting in ee annihilation as a function of th...

Measurement of Neutral Meson Production in Hadronic

The 7°r, qj, and w meson productions have been studied using 3 million hadronic Z events recorded with L3 detector at LEP. The meson production in the final sample, two-jet and three-jet event samples as well as in each jet have been measured and compared with the JETSET and HERWIG Monte Carlo predictions. The momentum distributions are measured and compared with Monte Carlo prediction and anal...
