Nuclear Physics of Double Beta Decay
Study of the neutrinoless ββ decay allows us to put a stringent limit on the effective neutrino Majorana mass, a quantity of fundamental importance. To test our ability to evaluate the nuclear matrix elements that govern the decay rate, it is desirable to be able to describe the allowed two-neutrino decay. It is argued that only low-lying virtual intermediate states are important for that proce...
متن کاملNuclear physics aspects of double beta decay
— Comprehensive description of the phenomenology of the ββ decay is given, with emphasis on the nuclear physics aspects. After a brief review of the neutrino oscillation results and of motivation to test the lepton number conservation, the mechanism of the 0νββ is discussed. Its relation to the lepton flavor violation involving charged leptons and its use as a diagnostic tool of the 0νββ mechan...
متن کاملThe Antisymmetrical Interaction in Beta-Decay Theory
~HE pmcess of beta-disintegration can be considered as a four-particle pmcess, i.e., a process in which four particles are created simultaneously. Thus, e.g. , the process leading to the emission of an electron can be considered as the creation of a proton, a neutrino, Rnd an electron in positive energy states, and of a neutron in a negative state. is known in nickel but it has been assigned' t...
متن کاملThe Antisymmetrical Interaction in Beta-Decay Theory
Forms of the beta-decay interaction are sought which are totally symmetric and totally antisymmetric to the interchange of any two of the particles involved in the emission, It is found that there is no symmetric interaction and one antisymmetric. The antisymmetric interaction allows transitions without change of parity and with a change of nuclear spin of either 0 or ~1, including 0~0. First f...
متن کاملNuclear structure and double beta decay
Study of the neutrinoless double beta decay, 0νββ, includes a variety of problems of nuclear structure theory. They are reviewed here. The problems range from the mechanism of the decay, i.e. exchange of the light Majorana neutrino neutrino vesus the exchange of some heavy, so far unobserved particle. Next, the proper expressions for the corresponding operator are described that should include ...
