44. Theory Challenges in Neutrinoless Double Beta Decay

Prof. Fedor Simkovic (Comenius University and JINR Dubna)

5/27/19, 9:30 AM

Oral Presentation

The recent progress in theoretical description of the 0νββ-decay is shortly reviewed. Several simplified benchmark scenarios within left-right symmetric models are discussed. The question is raised whether light and heavy neutrino contributions to 0νββ-decay are experimentally distinguishable. New modes of the double-beta decay are introduced. The present-day results of the calculation of...

45. Neutrino-nuclear responses and the value of the weak axial coupling

Prof. Jouni Suhonen (University of Jyväskylä)

5/27/19, 10:00 AM

Oral Presentation

The value of the weak axial coupling, g$_A$, has pervasive impact on neutrino-nucleus interactions in many fields: Nuclear astrophysics, neutrino physics and particle physics. In particular, nuclear beta decays and double beta decays, as also astro-(anti)neutrino-nucleus scattering and nuclear muon capture imply effective quenched or enhanced values of g$_A$, sometimes deviating a lot from the...
