Hunting Season at Ves


We present preliminary results of study of the ηπ − , η ′ π − and b 1 π-systems produced in the π − Be-interaction at 28 GeV /c. J PC = 2 ++ and 1 −+-waves resulted from the PWA have been fitted in each system separately to establish the nature of the 1 −+-wave. A hypothesis of the 1 −+-wave resonant nature in the ηπ − and η ′ π − has no statistically… (More)
