Abstract:
We study semi-classical multi-spin strings in the non-supersymmetric backgrounds of AdSAdS Black Hole and Witten's confining model. We consider constant radius strings with rotations along the isometries of the backgrounds. In the AdSAdS Black Hole, solutions exist only if there is a non-zero spin in the Black Hole part. In contrast with the AdSAdS background, we find solutions which although have no rotation in the S5S^5 part, have a regular λ\lambda expansion in the expression for large energy. In the near-extremal D3D_3 and D4D_4 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.
