Scale-invariant spectrum of Lee-Wick model in de Sitter spacetime
Yun Soo Myung, Taeyoon Moon
We obtain a scale-invariant spectrum from the Lee-Wick model in de Sitter spacetime. This model is a fourth-order scalar theory whose mass parameter is determined by . Th…
Cosmological three-coupled scalar theory for the dS/LCFT correspondence
Yun Soo Myung, Taeyoon Moon
We investigate cosmological perturbations generated during de Sitter inflation in the three-coupled scalar theory. This theory is composed of three coupled scalars ()…
Primordial massive gravitational waves from Einstein-Chern-Simons-Weyl gravity
Yun Soo Myung, Taeyoon Moon
We investigate the evolution of cosmological perturbations during de Sitter inflation in the Einstein-Chern-Simons-Weyl gravity. Primordial massive gravitational waves are composed…
Massive gravitational waves in Chern-Simons modified gravity
Yun Soo Myung, Taeyoon Moon
We consider the nondynamical Chern-Simons (nCS) modified gravity, which is regarded as a parity-odd theory of massive gravity in four dimensions. We first find polarization modes o…
New massive conformal gravity
Yun Soo Myung
We investigate the new massive conformal gravity which is not invariant under conformal transformations, in comparison to the massive conformal gravity. We find five polarization m…
