Abstract

High-statistics data on the reaction €-p†€+€-n at 8.06 GeV/c were obtained. An isobarmodel partial-wave analysis was performed for the €€ system. The (1275) meson was confirmed as a narrow IJPC=00-+ resonance. It decays through both € and μ. A narrow state with IJPC=00-+ was found in an €€ decay channel at 1.42 GeV. It has a prominent peak in a € decay mode. No significant E(1420) signal with IJPC=01++ was found near the mass region of 1.42 GeV.
