Cosmological birefringence due to CPT-even Chern-Simons-like term with Kalb-Ramond and scalar fields

Shih-Hao Ho, W. F. Kao, Kazuharu Bamba +1

We study the CPT-even dimension-six Chern-Simons-like term by including dynamical Kalb-Ramond and scalar fields to examine the cosmological birefringence. We show that the combined…
