Maths HEP Lunchtime Seminars: Looking beyond the Planck Scale via Horava-Lifshitz gravity
22 May 2009 13:00 in CM219
In this talk, I will try to look beyond the Planck scale with
primordial gravitational waves produced during inflation in Horava gravity.
I will show you that primordial gravitational waves are circularly
polarized due to parity violation. The chirality of primordial
gravitational waves is a quite robust prediction of Horava gravity
which can be tested through observations of cosmic microwave
background radiation and stochastic gravitational waves.
