The Polarizability of the Deuteron
Abstract
The scalar and tensor polarizabilities of the deuteron are calculated using the recently developed effective field theory that describes nucleon-nucleon interactions. Leading and next-to-leading order contributions in the perturbative expansion predict a scalar electric polarizability of 0.595 fm3. The tensor electric polarizability receives contributions starting at next-to-leading order from the exchange of a single potential pion and is found to be -0.062 fm3. We compute the leading contributions to the scalar and tensor magnetic polarizabilities, finding 0.067 fm3 and 0.195 fm3, respectively.
