Nneutrinoless double beta decay pdf free download

Neutrinoless double beta decay and direct searches for neutrino. An erc project to study nuclear reactions for neutrinoless double beta decay. In particular, observation of this decay would demonstrate that the neutrino is a majorana particle and that lepton number conservation is violated in nature. The impact of the evidence obtained for neutrinoless double beta decay in this paper best value of the effective neutrino mass m 0.

Study of the neutrinoless double beta decay, 0\nu\beta\beta, includes a variety of problems of nuclear structure theory. Today neutrinoless double beta decay faces a new era where largescale. Neutrinoless double beta decay 0\nu\beta\beta is considered the best. The various detection schemes for double beta decay are outlined elsewhere 1, so we merely mention the salient points here. The process can be mediated by an exchange of a light majorana neutrino, or by an exchange of other particles.

Observationofneutrinoless double beta 0 decay would signal violation of total lepton number conservation. Particle physics is important since it provides the mechanisms for neutrinoless double beta decay. Neutrinoless double beta decay is a hypothesised nuclear process in which two neutrons simultaneously decay into protons with no neutrino emission. The prized observation of this decay would point to the existence of a process that violates a fundamental symmetry of the standard model of particle physics, and would allow to establish the nature of neutrinos. The aim of this experiment is to search for neutrinoless decay and investigate two neutrino double beta decay in seven different enriched isotopes 100mo, 82se, 48ca, 96zr, 116cd, te and 150nd. The program is intended to bring together experts in effective field theory, manybody theory, bsm physics, and experiment to address outstanding problems associated with the matrix elements that govern neutrinoless doublebeta decay. To operate a ge detector, a reverse bias voltage is applied which sweeps free holes to the negative. We will emphasize specific topics each week and hold both an initial and a concluding workshop.
