0. Coherent target effects for atomic neutrino mass spectroscopy and detection of relic neutrino

Motohiko Yoshimura (Okayama University)

New experimental method using isolated atoms and molecules implanted in sold matrix is explained, whose goal is to measure all 3 neutrino masses and the unknown mixing angle along with determination of Majorana or Dirac particle. If the method works, it is expected to detect the cosmic relic neutrino, too.

14. Emergent Electroweak Gravity

We show that the cosmic neutrino background is a superfluid today, and the quantum numbers of the order parameter give a goldstone graviton, with a coupling numerically similar to the actual Newton's constant.

12. Relic neutrino detection using beta decaying nuclei

Dr Alfredo Giuseppe Cocco (Istituto Nazionale di Fisica Nucleare)

We present a study on the interaction of low energy electron neutrinos on nuclei that undergo both beta decay and electron capture. We show that, due to the absence of an energy threshold and to the relatively high value of the cross section, these processes are the only ones to date having a realistic chance to unambiguously detect the yet undiscovered cosmological...

13. Experimental challenges towards the detection of relic neutrinos with unstable nuclei

Dr Marcello Messina (University of Bern)

In this talk I will review the experimental challenges towards the detection of relic neutrinos. The talk is based on a paper where the idea of detecting relic neutrinos with instable nucli is renewed. Different target nucli and experimental approaches are considered and, the advantage and the difficulties of different experimental techniques are discussed.
