Abstract

Results of the measurement of the φ meson parameters with the general purpose detector CMD-2 at the upgraded e+e- collider VEPP-2M at Novosibirsk are presented. This is the first measurement of the four major φ decay modes in a single e+e- experiment. The results based on about 55,600 identified hadronic events are consistent with previous measurements, and have precision comparable to the current world average.
