Engineering a Bosonic AdS / CFT Correspondence 1

We search for a possible bosonic (i.e. non-supersymmetric) string/gauge theory correspondence by using ten-dimensional IIB and 0B strings as a guide. Our construction is based on the low-energy bosonic string effective action modified by an extra form flux. The closed string tachyon can be stabilyzed if the AdS scale L does not exceed certain critical value, L < L c. We argue that the extra form may be non-perturbatively generated as a soliton from 3-string junctions, similarly to the known non-perturbative (Jackiw-Rebbi-'tHooft-Hasenfratz) mechanism in gauge theories. The stable AdS 13 × S 13 solution is found, which apparently implies the existence of a 12-dimensional AdS-boundary conformal field theory with the SO(14) global symmetry in the large N 't Hooft limit. We also generalize the conjectured bosonic AdS/CFT duality to finite temperature, and calculate the 'glueball' masses from the dilaton wave equation in the AdS black hole background, in various space-time dimensions.
