Lecturer: Dr. Doron Gazit Affiliation: Racah Institute of Physics, Hebrew University of Jerusalem 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.
