29. Precise Q-Value Measurements for Neutrino Physics

Dr Sergey Eliseev (Max-Planck Institute for Nuclear Physics)

Oral

The list of open issues in neutrino physics is long. We do not know, for instance, the absolute neutrino mass value, the neutrino type (Majorana or Dirac), or whether there are sterile neutrinos. Penning-trap mass spectrometry can help solve some of these issues by determining the *Q*-values of certain beta and double-beta processes with high precision. This contribution will give a brief...

13. Double-charge exchanges for double beta decays

Oral

The reach of neutrinoless double-beta (0νββ) decay searches that aim to observe lepton number violation and show that neutrinos are Majorana particles, depends on the nuclear matrix elements that govern the decay. The calculated nuclear matrix elements, however, suffer from several limitations. Predicted matrix-element values depend on the many-body method used to obtain them and, in addition,...

102. Dark pion dark matter : WIMP vs. SIMP

Pyungwon Ko (KIAS)

Oral

In this talk, I discuss a possibility that dark matter is a composite dark pion in the strongly interacting hidden sector. Depending on the mass scale of dark pion and couplings, it could make either weakly interacting massive particle (WIMP) or strongly interacting massive particle (SIMP).
