Abstract
We study extremal and nonextremal generalizations of the regular nonabelian monopole solution of [23], interpreted in [9] as 5branes wrapped on a shrinking S2. Naively, the low energy dynamics is pure N = 1 supersymmetric YangMills. However, our results suggest that the scale of confinement and chiral symmetry breaking in the YangMills theory actually coincides with the Hagedorn temperature of the little string theory. We find solutions with regular horizons and arbitrarily high Hawking temperature. Chiral symmetry is restored at high energy density, corresponding to large black holes. But the entropy of the black hole solutions decreases as one proceeds to higher temperatures, indicating that there is a thermodynamic instability and that the canonical ensemble is illdefined. For certain limits of the black hole solutions, we exhibit explicit nonlinear sigma models involving a linear dilaton. In other limits we find extremal nonBPS solutions which may have some relevance to string cosmology.
