Applications of an improved bag model

Abstract

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 B1/4(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 TH 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.
