Helicity nonconservation in diffraction production of the b1-(1235) mesons in the π-P→b1-P reaction

Creators

Description

Investigation of diffractive formation of b1-(1235) mesons in the π-p→b1-p reaction is concluded, and angular characteristics of the decay b1-→π-ω0 are studied. Based on the obtained data it is shown, that the mechanism of b1- meson production in this reaction does not depend on energy and it is responsible for helicity nonconservation both in s- and in t-channels
