Abstract
We argue that there are generic solutions to the type 0 gravity equations of motion that are confining in the infrared and have log scaling in the ultraviolet. The background curvature generically diverges in the IR. Nevertheless, there exists a solution where higher order string corrections appear to be exponentially suppressed in the IR with respect to the leading type 0 gravity terms. The existence of this solution requires a nonzero but constant tachyon expectation value. We show that the generic solutions lead to a long range linear quark potential, magnetic screening and a mass gap. We also compute some WKB glueball mass ratios and find results that are in reasonable agreement with lattice computations.
