Observation of exotic meson production in the reaction ${\pi }^{-}p\to {\eta }^{\prime }{\pi }^{-}p$ at 18 GeV/c

E. I. Ivanov

An amplitude analysis of an exclusive sample of 5765 events from the reaction ${\pi }^{-}p\to {\eta }^{\prime }{\pi }^{-}p$ at 18 GeV/c is described. The ${\eta }^{\prime }{\pi }^{-}$ production is dominated…
