CALCULATION OF THE ETA AND ETA-' MASSES IN THE BAG MODEL
Journal or Book Title
PHYSICAL REVIEW D
The annihilation contribution to the masses of the JPC=0-+ isoscalars is calculated in the bag model. The resultant mass shift for the η′ is large and positive. For αs=1.15 we obtain mη=0.53 GeV and mη′=0.965 GeV, leading to a good description of pseudoscalar masses within the model.
