Abstract: Neutrinoless double-beta decay is a phenomenon searched for intensively by many researchers. Its half-life would give a crucial input for determining the effective neutrino mass, if the decay occurs. This determination is one of the most important subjects in modern physics.
Theorists need to calculate another input, that is, the transition matrix element of this decay. The nuclear factor in the matrix element, called nuclear matrix element, is difficult to obtain accurately because of two reasons. One is that this quantity cannot be obtained experimentally. Second, approximation is essential for calculating the nuclear wave functions of the initial and final states. In this seminar I will present my calculation of the nuclear matrix element of 48Ca -> 48Ti putting emphasis on how the experimental data of the half-life of the two-neutrino double-beta decay and the Gamow-Teller transition strength functions help the theoretical calculations.
