What New Physics Can Double Beta Decay Experiments Hope to See?
Abstract
Double-beta decay experiments have been traditionally interpreted in terms of
the Gelmini-Roncadelli triplet majoron model, which has been ruled out by LEP.
We briefly survey here the kinds of physics to which these experiments might be
sensitive in the light of the LEP constraints. We identify six broad categories
of models, including some new categories which have not been previously
considered.
