Abstract:
Neutrinoless double beta decay is a
very sensitive test for lepton number
violation. In models which include
small deviations from the Standard
model, this decay is related to the
character of the neutrino as a Majorana
fermion, and to its mass. In all models,
the strength of the decay is
proportional to the nuclear matrix
element. The calculation of these
matrix elements is the main
uncertainty source in the experiments
and their analysis. Moreover, for such
a rare decay, understanding the
sensitivity of the measurement is very
important in order to state the
effectiveness of this experiment, with
respect to other methods, such as the
cosmological constraints on the
number of neutrino species and their
masses. In this talk I will give an
overview on the status of the
calculations and possible new
directions towards better control on the
many body calculations and their
predictions.
