TESTING CPT SYMMETRY WITH CURRENT AND FUTURE CMB MEASUREMENTS
TESTING CPT SYMMETRY WITH CURRENT AND FUTURE CMB MEASUREMENTS
In this paper, we use the current and future cosmic microwave background (CMB) experiments to test the Charge–Parity–Time Reversal (CPT) symmetry. We consider a CPT-violating interaction in the photon sector , which gives rise to a rotation of the polarization vectors of the propagating CMB photons. By combining the 9 …
