Study of Nonstrange Mesons Produced inK−pInteractions at 3.9 and 4.6 GeV/c

An investigation is presented on the production and decay properties of pseudoscalar, vector, and tensor mesons produced in association with $\Lambda$, ${\Sigma }^0$, and $Y^{*}\mathrm{}\left(1385\right)\mathrm{}$ from $K^{-}p$ interactions at 3.9 and 4.6 GeV/c. The data have been compared with SU(3) and quark-model predictions. New measurements of the mass, width, and branching ratios of the $\phi \mathrm{}\left(1019\right)\mathrm{}$, $f^{\prime }\mathrm{}\left(1519\right)\mathrm{}$, and $Y^{*}\mathrm{}\left(1385\right)\mathrm{}$ resonances are given. Our analysis of the ${\eta }^{\prime }$ meson favors the $J^{\mathrm{PC}}=0^{-+}$ classification. The properties of this well-known meson are compared with those of our previously proposed $M\left(953\right)\mathrm{}$ meson. An important aspect of this study is that we have placed particular emphasis on taking the background into account when we extracted resonance quantities such as the density-matrix elements.
