Production ofKππResonances at High Energy

Abstract

The previously observed enhancement between 1100 and 1400 MeV in the $K\pi \pi$ mass spectrum is interpreted as a $T=\frac{1}{2}$, $J^P=1^{+}$ resonance at 1280±20 MeV and width of 130 ± 15 MeV which decays into $\pi +K^{*}$ and into $K+\rho$. Evidence is also presented supporting the existence of the newly reported $L$ meson.
