Gravitational Leptogenesis and Its Signatures in CMB
Bo Feng, Hong Li, Mingzhe Li, Xinmin Zhang
Abstract
We study the phenomenologies in astrophysics and particularly in CMB associated with the gravitational leptogenesis. Our results show that future CMB polarization experiments, such as PLANCK and CMBpol will make a possible test on this class of model for leptogenesis.
