S. Suzukiat7,J. Va’Vra ‘p2, S. Williams’. We present evidence for the existence of two strange Jp = l- mesons; one at 1410 MeV/c2 coupling principally to K*(892)n, and the other at 1790 MeV/c2 coupling to K Z, K*a and PK. The data derive from a partial wave analysis of the K07r+7rr- system produced in the reaction K-p + K”rT+7rT-n at 11 GeV/c. The production mechanism and quark model assignment of each state are discussed. The state at 1410 MeV/c2 is most naturally T/E understood as the first radial excitation of the K*(892), and the 1790 MeV / c2 object can be interpreted as the triplet D wave partner to the 3- K * (1780)
