Recent experimental studies are reviewed on neutrino nuclear responses (square of nuclear matrix element NME) for double beta decays and astro neutrino interactions.The NMEs are re-normalized (quenched) by nucleonic and non-nucleonic correlations. The experimental studies to be discussed include single and double charge exchange reactions, muon capture reactions, photo-nuclear reactions and so...

The recent progress in theoretical description of the 0ฮฝฮฒฮฒ-decay is shortly reviewed. The 0ฮฝฮฒฮฒ-decay with the inclusion of the right-handed leptonic and hadronic currents and by assuming exchange of both light and heavy neutrinos is revisited. The possibility to discriminate between different 0ฮฝฮฒฮฒ-decay mechanisms by using data on 0ฮฝฮฒฮฒ-decay half-lives of different nuclei is addressed. Subject...

8B solar neutrino measurements from SNO and Super-Kamiokande have clearly demonstrated solar neutrino flavor conversion and determined neutrino oscillation parameters driving this conversion.

In a new theoretical approach, it is shown that heavy ion charge exchange reactions are appropriate for probing nuclear response functions of the same type as encountered in single and double beta decay. In particular, a special class of nuclear double charge exchange (DCE) reactions proceeding as a one-step reaction through a two-body process are shown to involve nuclear matrix elements of...

Crystal scintillators possess certain advantages for investigations of rare alpha, beta and double beta decays thanks to presence of the element of interest in the crystal scintillator compound, that provides almost 100% detection efficiency to the effect searched for.

The evaluation of nuclear matrix elements is one of the cornerstones of the theoretical description of neutrinoless double beta decay rates. Unfortunately, different state-of-the-art structure calculations show very different results when computing them. Nucleon-nucleon pairing correlations are essential ingredient, it is thus important to devise experimental probes sensitive to the relevant...

We still do not know if the neutrino is a Majorana or a Dirac particle, i.e. if the neutrino is its own antiparticle or not. Also the absolute mass scale of the neutrino is unknown, only the relative scale is known from the neutrino-oscillation experiments. These unknown features of the neutrino can be tackled by experiments trying to detect the neutrinoless double beta (0ฮฝฮฒฮฒ) decay. The rate...

In this talk, the importance of the so called "neutrinoless double beta decay" transition in the search for physics beyond the Standard Model is emphasized. The expectations for the transition rate are examined in the assumption that ordinary neutrinos have Majorana masses.

The assessment of the neutrino absolute mass scale is still a crucial challenge in today particle physics and cosmology.

Variety of spin and isospin responses is among the most interesting features in atomic nuclei. For the spin-isospin response, the Gamow-Teller (GT) transition is the simplest within one-phonon excitations, and it has been well studied. In contrast, data on multi-phonon excitations have been scarce. The double GT giant resonance (DGTGR) is the simplest two-phonon excitation mode in spin-isospin...

The mass of the nucleus reflects the total energy of this many-body system and thus is a key property for a variety of nuclear structure and fundamental investigations. Penning-trap mass spectrometry has pushed in recent years the limits of sensitivity, resolution and accuracy tremendously.

Neutrinoless double beta decay (0vbb) is the only practical way to understand the neutrino nature (Dirac or Majorana particle) and to observe full lepton number violation required by most beyond the standard model theories.

The main goal of the SuperNEMO experiment is to search for...
