Abstract
Using the response theory approach, the mean current due to tunneling of Cooper pairs in microwave driven superconducting junctions coupled to an electromagnetic environment is derived. The noise power spectrum is calculated showing shot noise behaviour due to the stochastic char acter of Cooper pair tunneling if the Josephson coupling energy is muc h smaller than the charging energy.
