23. Neutrino masses, double beta-decay nuclear matrix elements and quenching of axial-vector coupling constant

Prof. Fedor Simkovic (Comenius University and JINR Dubna)

29/06/2018, 09:20

Oral

The present-day results of the calculation of the 0νββ-decay nuclear matrix elements are discussed. The progress in the calculation of the double beta decay NMES within the QRPA is presented. A connection between the 2νββ-decay and 0νββ-decay matrix elements is analyzed. An impact of the quenching of the axial-vector coupling constant on double-beta decay processes is investigated and a novel...

37. Neutrino nuclear responses for astroneutrinos and double beta decays

Prof. Hiroyasu Ejiri (RCNP, Osaka University)

Oral

We report briefly recent studies of neutrino nuclear responses for astro-neutrinos and double beta decays by using charge exchange reactions (CERs). Neutrino nuclear responses (square of nuclear matrix elements NMEs) are crucial for neutrino studies in nuclei. Subjects discussed include experimental studies of nuclear muon and neutrino CERs at RCNP Osaka Univ. and the re-normalization...

87. Neutrino properties and their astrophysical consequences

Prof. Baha Balantekin (University of Wisconsin, Madison)

29/06/2018, 10:20

Oral

A brief survey of our present understanding of neutrino properties will be presented. A good fraction of the heavier nuclei were formed in the rapid neutron capture (r-process) nucleosynthesis scenario. Although an astrophysical site of the r-process is not yet identified, one expects such sites to be associated with explosive phenomena since a large number of interactions are required to take...
