54. What’s up with dark matter? - Direct dark matter searches

Federica Petricca (Max-Planck-Institut für Physik)

26/06/2018, 15:00

Invited

The dark matter problem has accompanied cosmologist and particle physicist for more than 80 years. Nowadays we have an extremely accurate model of our Universe, but still most of its content eludes our observation. The observation of this missing matter is of compelling necessity for our understanding. Direct searches aim to detect dark matter particles with Earth-bound detectors. A review...

205. Review on Neutrinoless Double Beta Decay

Matthias Laubenstein (INFN - LNGS)

26/06/2018, 15:30

Invited

The observation of neutrino oscillations has established non-zero masses of neutrinos, the flavour change and mixing of neutrinos. After these discoveries the global physics community is facing the next challenging problem, whether neutrinos are indeed Majo- rana particles (i.e. identical to its own antiparticle). The search for neutrinoless double beta decay allows in principle fixing of the...

38. Impact of Neutrino Collective Oscillation on Supernova Nucleosynthesis and Mass Hierarchy

Taka Kajino (National Astronomical Observatory of Japan)

Oral

Binary neutron-star mergers (NSMs) and core-collapse supernovae (CCSNe, both neutrino-driven winds; ν-wind SNe and magneto-hydrodynamic jets; MHD Jet-SNe) are viable candidate astrophysical sites for the heavy r-process elements. In particular, the observed optical and near-infrared emissions from GW170817 are consistent with those from radiative decays of r-process nuclei which are predicted...

126. The impact of axions on Mup

Inma Dominguez (Universidad de Granada)

Oral

Axions are weak interactive bosons early introduced to solve the longstanding CP violation problem of strong interaction. If their mass is small enough (few keV or smaller), they can be produced in stellar interior, e.g., by Compton, Bremsthalung, pair annihilations or Primakoff processess, acting as an additional energy loss mechanism. We study the effect of axions in the evolution of...

5. The Neutrino Signal From Pair Instability Supernovae

James Kneller (NC State University)

26/06/2018, 16:30

Oral

Pair-instability supernovae (PISNe) are the explosions of very massive stars with carbon-oxygen cores in the range of 64 Msun to 133 Msun. These kind of supernovae are candidates for some observed superluminous supernovae although recent studies suggest PISNe in the local Universe may be much dimmer and hidden among other supernova classes. While observations of PISNe using electromagnetic...

170. Neutrinos from Presupernova Stars

Takashi Yoshida (University of Tokyo)

26/06/2018, 16:45

Oral

Some evolved massive stars such as Betelgeuse and Antares are located at the distance of hundreds parsec. When such a star explodes as a supernova, neutrino events will be observed by current and future neutrino detectors even before the supernova explosion, i.e., the neutrinos from the presupernova star will be detected. The neutrino event rate in neutrino detectors during silicon burning of...
