Quasirotational Disturbances of Linear String Baryon Configuration

Abstract

For the linear string baryon model $q$-$q$-$q$ the small disturbances of its rotational motion (quasirotational states) are investigated. The spectrum of these states is obtained in the form of Fourier series and the complex eigenfrequencies are found in this spectrum. So the classic rotational motions of the linear string baryon model are unstable (unlike the similar motions for the string with massive ends). This instability differs from its analog for the three-string baryon model.
