The standard scenario of cosmology which includes only Compton scattering predicts a measurable amount for the linear polarization of the cosmic microwave background (CMB) radiation, while trough this scenario there is no any sources to generate circular polarization. The circular polarization of CMB has not been observed so far, however it has not been completely excluded from observational evidences, for example, SPIDER group constraints on l(l+1)CVl/(2�?) for 33
