AbstractWe show that if the gravitational Chern-Simons term couples to a massive scalar field (m > H), the primordial gravitational waves (GWs) will show itself the chirality oscillation, i.e., the amplitudes of the left-and right-handed GWs modes will convert into each other and oscillate in their propagations. This oscillation will eventually develop a permanent difference of the amplitudes of both modes, which leads to nearly opposite oscillating shapes in the power spectra of the left-and right-handed primordial GWs. We discuss its implication to the CMB B-mode polarization.
