| Popis: |
Abundant production of the established $L$ meson and also of the possible $Q$ meson are observed in coherent production, ${K}^{\ensuremath{-}}d\ensuremath{\rightarrow}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}d$, at 12.6 BeV/c. This is the first observation of $L$-meson production on nuclei. The $Q$ and $L$ isospins are unambiguously determined to be \textonehalf{}. The $L$ is observed to be produced polarized. A striking resemblance between the final states ${K}^{*}(890)\ensuremath{\pi}d$ and ${K}^{*}(1400)\ensuremath{\pi}d$ is observed with these final states being related to the $Q$ and $L$ mesons, respectively. |
