Axionic Extensions of the Standard Model

Abstract

After a brief review of the axion solution of the strong CP problem, its supersymmetric extension and the superstring axion are discussed. I also present one interesting cosmological scenario, the axino-gravitino cosmology, for the large scale structure of the universe.
