Measurements of the parameters of the phi(1020) resonance through studies of the processes e(+)e(-vertical bar)-> K+K-,KSKL, and pi(+)pi(-)pi(0) - art. no. 072002

The cross sections of the processes e(+)e(-) -->K+K-, e(+)e(-) -->KsKL, and e(+)e(-) --> pi (+)pi (-)pi (0) were measured in the SND experiment at the VEPP-2M collider in the energy region near the phi (1020) meson. These mea surements were based on about 10(6) K+K-, 0.5x10(6) KsKL, and 0.4x10(6) pi (+)pi (-)pi (o) selected events. The measured cross sections have been anal yzed in the framework of the vector meson dominance model and the main para meters of the phi resonance were obtained, such as its mass, width, the pro duction cross section, and branching ratios of the main decay modes. The me asured value of the phi mason total width, Gamma (phi)=4.21 +/-0.04, is low er than the present world average of 4.458+/-0.032 MeV. Contributions in ad dition to the conventional vector meson dominance model were found in the e (+)e(-) --> pi (+)pi (-)pi (o) reaction cross section.
