Interplay between strong, weak and electromagnetic interactions revealed by nuclear decay processes

. - We discuss a beyond-the-mean-field theory of alpha-decay, namely a solution to the alpha-decay problem through the use of the Hartree-Fock-Bogoliubov (HFB) method together with a residual nucleon-nucleon Surface Gaussian Interaction (SGI), a generalization of the well-known Surface Delta Interaction. We present a systematic description of the alpha-particle formation amplitude in superfluid nuclei in terms of microscopic degrees of freedom, namely protons and neutrons. This opens a path towards the understanding of a less-known interplay between the fundamental interactions explored through decay processes, namely the interplay between the alpha-particle formation amplitude and electromagnetic observables or electron capture transition strengths.
