摘要：

We show that a nonminimal coupling of electromagnetism with background torsion can produce birefringence of the electromagnetic waves. This birefringence gives rise to a B-mode polarization of the CMB. From the bounds on CMB polarization from QUaD experiment, one can put limits on the background torsion xi T-1(i) = (2.78 +/- 4.85) x 10(-20) GeV-1.
