Axions and the Strong CP Problem in M-theory


We examine the possibility that the strong CP problem is solved by stringtheoretic axions in strong-coupling limit of the E8×E 8 heterotic string theory (M -theory). We first discuss some generic features of gauge kinetic functions in compactified M -theory, and examine in detail the axion potential induced by the explicit breakings other than the QCD… (More)
