Mass ratios for the SU(4) terms of the 20-multiplet and search for B mesons

V. V. Khrushchev

Abstract

The mass ratios for the U(4) terms of the 20-multiplet were determined with an accuracy to isotropic splitting. The possibility of including the Y meson in the 20-multiplet composition, which is consistent with the existing experimental data, is considered. The mixing angles in the (20+1) multiplet and the masses of the terms of the 20-multiplet of the I/sup - -/ mesons are determined.
