摘要:

通过引入动力学Kalb-Ramond场和标量场来研究CPT偶维六Chern-Simons类项的宇宙学双折射。结果表明,中微子流和Kalb-Ramond场的联合作用可以在宇宙微波背景辐射极化中产生相当大的旋转极化角。

英文摘要:

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 effect of neutrino current and Kalb-Ramond field could induce a sizable rotation polarization angle in the cosmic microwave background radiation polarization.
