Kallosh, Renata2017-05-232017-05-232017-05https://hdl.handle.net/11299/188214We discuss alpha-attractor cosmological models which can be derived by a consistent reduction from theories with maximal supersymmetry, like M-theory, superstring theory, or maximal supergravity, to minimal supersymmetry models. These models provide a set of targets for the future detectors of primordial gravitational waves, scanning the region of tensor to scalar ratio between 1/100 and 1/1000.enFTPIOLIVEFESTPresentation
