Cosmology and Gravitation Theories

We find the gravity solution corresponding to a large number of Neveu-Schwarz or D5-branes wrapped on a two sphere so that we have pure $N\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1$ super Yang-Mills in the IR. The supergravity solution is smooth, it shows confinement, and it breaks the $\mathrm{U}(1{)}_{R}$ chiral symmetry in the appropriate way. When the gravity approximation is valid the masses of glueballs are comparable to the masses of Kaluza-Klein (KK) states on the 5-brane, but if we could quantize strings on this background it looks like we should be able to decouple the KK states.
