32. Current topics in weak interaction processes

Sabin Stoica (CIFRA)

We briefly review the investigation of some current topics in weak interaction processes. First, we present some methods used to get the electrons’ wave functions emitted in these processes. Next, we use these wave functions to compute relevant kinematic quantities such as Fermi functions, phase space factors, electron spectra and angular correlation between the emitted electrons. Further, we...

21. Neutrinoless Double-Beta Decay & Realistic Shell Model

Nunzio Itaco (Università della Campania "Luigi Vanvitelli" & Istituto Nazionale di Fisica Nucleare)

I'll report on the calculation of the nuclear matrix element for the neutrinoless double-β decay process using the realistic shell model.
In this approach, we start from a realistic nucleon-nucleon potential and then derive the effective shell-model Hamiltonian and 0νββ decay operator within the many-body perturbation theory.
I'll focus my attention on a few candidates for the 0νββ decay...

6. Recent progress with the nuclear matrix elements for double beta decay

Mihai Horoi (Central Michigan University)

In my talk I will review recent progress in calculations of the nuclear matrix elements for two-neutrino double beta decay, two-neutrino double electron capture double beta decay, and neutrinoless double beta decay. Emphasis will be on the extension of the strength function approach for the two-neutrino decay matrix elements, and on the statistical approach to estimate the neutrinoless nuclear...
