Gravitational Waves as Probes for New Physics Gravitational Waves as Probes for New Physics

Speaker

Prof. Robert Brandenberger (McGill University)

Description

I will argue that the slope of the spectrum of
gravitational waves may provide us evidence of
superstring effects in early universe cosmology. Both
String Gas Cosmology and the S-Brane Mediated Ekpyrotic
scenario predict a blue tilt of the tensor spectrum.
