Stringlike solutions of the bag model

Abstract

It is shown that bags made of colored quarks and gluons have an asymptotically linear Regge trajectory whose structure is dominated by colored flux lines. The slope is calculated and found to be given by ${\alpha }^{\prime }=0.88\mathrm{}$ Ge${\mathrm{V}}^{-2\mathrm{}}$. The relationship to the dual string model is discussed and speculations are made about the possible relevance of the picture for approximate duality.
