The reactions K - + p → pseudoscalar meson + Λ (1520) at 4.2 GeV/ c
Abstract
The total and differential cross sections of the reactions K -p → π 0Λ (1520), ηΛ(1520) and η' Λ(1520) have been measured. Prominent forward peaks are onserved in all three reactions. The first reaction shows also a backward peak. The spin density matrix elements of the Λ(1520) in this reaction are determined. For forward production the results show a remarkable alignment of the Λ(1520) corresponding to an M2 transition in the model of Stodolsky-Sakurai for {3}/{2}- baryon production.
