Abstract
In this Letter we revise the cosmological bounds on the kinetic mixing parameter and in the case of exact mirror parity set an upper limit ϵ<3Ã10â10. Much weaker limit can be obtained in the case of asymmetric mirror sector, with an electroweak symmetry breaking scale larger than the ordinary electroweak scale.
