Abstract
In this paper we have investigated the properties of the D(1285) and E(1420) meson resonances using the five-body annihilation channels p̅p →KK̅πππ obtained in a large statistics experiment (28 events/μb). The analysis favours the 1+ spin-parity assignment for the D(1285) meson. The dominant decay mode of the D(1285) into KK̅π is found to be δ(970)π. The situation concerning the E(1420) meson remains confused although not inconsistent with previous analyses. Partial cross sections on resonance production are also presented.
