φ- Meson Production in e+e- Annihilations at 29 GeV
Abstract
Production of φ mesons in e+e- annihilation at a center-of-mass energy of 29 GeV has been observed with the time-projection chamber detector at the PEP storage ring. The φ production rate has been measured in the energy range 0.075<x<0.55 (x=2Eφs), giving 0.077+/-0.012(stat)+/-0.016(syst) φ's per event. The average value of pt2 relative to the thrust axis is 1.0+/-0.4 (GeV/c)2.
