The BRAIN CMB polarization experiment
In the standard cosmological scenario tensor perturbations of the metric produce a rotational component in the Cosmic Microwave Background polarization, called B-modes. The expected signal is of the order of similar to 0.1 mu K, well beyond the sensitivity of current experiments. In this paper, we i...
