New results in the partial wave analysis of the K(sup (minus))omega system in the reaction K(sup (minus))p yields K(sup (minus))pi(sup +)pi(sup (minus))pi(sup 0)p

摘要

Preliminary results are presented from the first large-statistics partial wave analysis of K(sup (minus))(omega) system produced in the reaction K(sup (minus)p (yields) K(sup (minus))(pi)(sup +)(pi)(sup (minus))(pi)(sup 0)p at 11 GeV/c observed with the LASS spectrometer at SLAC. The analysis is based on the moments of the joint angular distributions of the decay to the K(sup (minus))(omega)) system, with subsequent (omega) decay to (pi)(sup +)(pi)(sup (minus))(pi)(sub 0). The resulting J(sup P) = 2(sup (minus)), 2(sup +) and 3(sup (minus)) amplitudes exhibit resonant behavior, and are discussed in the context of the relevant Briet-Wigner fits.
