Exclusive Hadronic Final States in E+ E- Interactions at BaBar
Abstract
The first observation of e{sup +}e{sup -} annihilation into states of positive C parity, {rho}{sup 0}{rho}{sup 0} and {phi}{phi}{sup 0} is reported. It is shown that these final states are produced through two-virtual-photon annihilation. this is based on the distributions of cos{theta}*, where {theta}* is the center-of-mass polar angle of {phi} or {rho}{sup 0}. The cross sections for the |cos{theta}*| < 0.8 are measured. In addition, the observation of another channel, e{sup +}e{sup -} {yields} {phi}{eta} near {radical}s = 10.58 Gev with a significance of 6.5{sigma} is discussed. The cross section of the later channel for |cos{theta}*| < 0.8 is measured, where {theta}* is the center-of-mass polar angle of {phi} meson.
