Query: Neutrinoless double beta decay and new physics in the neutrino sector   Neutrinoless double beta decay belongs to the most sensitive tools for the
search of new physics beyond the standard model. The recent half life limit of
the Heidelberg-Moscow experiment implies restrictive bounds on the absolute
mass scale in the neutrino sector. Possible improvements by the GENIUS project
provide a unique possibility to reconstruct the neutrino mass spectrum. Further
constraints on new interactions in the neutrino sector are given in a
model-independent way. Consequences for neutrino anomalies and theories beyond
the standard model such as left-right symmetric models, R-parity violating SUSY
and leptoquarks are discussed. The potential of double beta decay experiments
in the search for WIMP dark matter is reviewed.
