Applications of an improved bag model

Summary, in English

Phenomenological consequences of a recently improved and unified study of the lowestlying hadrons in the MIT Bag model are explored. In contrast to earlier fits we find the new values for the Bag constant B^1/4(200-230 MeV) and the hadronic radii R₀(≈3.2 GeV^-1) to be consistent with present estimates of the gluon condensate {Mathematical expression}, the Hagedorn temperature T_H and experimental hyperon decay rates. We also calculate the {Mathematical expression} spectrum within the same MIT Bag model framework and find for the exotic state m₁-+≃1400 MeV. This result roughly agrees with earlier estimates using different methods and parameters.
