Summary: 

In this paper we show that the presence of topological defects in the cosmic micorwave background (CMB) can be discovered most easily when looking at a specitic form of polarization of the CMB, so called B-polarization. Defects leave a stronger signature in the B-polarization than e.g. in the temperature anisotropy.
