Rare decay modes of K*(1420) and K*(892)

Abstract:
A 2.5 standard deviation signal is observed for the decay K*-(1420) → K*-(892)π+π-. From this signal a partial width of 13.0 ± 5.0 MeV for the decay mode K*(1420)→K*(892)ππ is deduced under the assumption that the ππ system is in an I = 1 state. For the rare decay mode K*(892)→Kππ no signal is observed. The following upper limits can be given for the decay widths: ΓK*-(892) → K-π+π- < 40 keV, ΓK*-(892) → K0π-π0 < 35 keV, ΓK*0(892) → K0π+π- < 35 keV. © 1978.
