Abstract:
We study semi-classical multi-spin strings in the non-supersymmetric backgrounds of Black Hole and Witten's confining model. We consider constant radius strings with rotations along the isometries of the backgrounds. In the Black Hole, solutions exist only if there is a non-zero spin in the Black Hole part. In contrast with the background, we find solutions which although have no rotation in the part, have a regular expansion in the expression for large energy. In the near-extremal and backgrounds, we find that strings have to be located on the confining wall. We also discuss the stability of solutions by considering the fluctuation Lagrangians.- gravitation
