The Cap in the Hat: Unoriented 2D Strings and Matrix(-Vector) Models
arXiv:hep-th/0311068 · doi:10.1088/1126-6708/2004/01/043
Abstract
We classify the possible bosonic and Type 0 unoriented string theories in two dimensions, and find their dual matrix(-vector) models. There are no RP^2 R-R tadpoles in any of the models, but many of them possess a massless tachyon tadpole. Thus all the models we find are consistent two-dimensional string vacua, but some get quantum corrections to their classical tachyon background. Where possible, we solve the tadpole cancellation condition, and find all the tachyon tadpole-free theories.
