| RES-NOVA: A revolutionary archaeological Pb observatory for astrophysical neutrino sources |
| Speaker: | Luca Pattavina (LNGS/ TU München) |
| Abstract: | The RES-NOVA project was recently granted an ERC Consolidator for hunting neutrinos from core-collapse supernovae (SN) via coherent elastic neutrino-nucleus scattering (CEνNS) using an array of archaeological lead (Pb) based cryogenic detectors. The high CEνNS cross-section on Pb and the ultra-high radiopurity of archaeological Pb enable the operation of a highly sensitive neutrino observatory, equally sensitive to all neutrino flavors, with dimensions at the cm-scale. The first phase of the RES-NOVA project is planning to operate a demonstrator detector with a total active volume of (30 cm)^3. It will be sensitive to SN bursts from the entire Milky Way Galaxy with >3Ï sensitivity, while running PbWO_4 detectors with 1 keV energy threshold. The main SN parameters can potentially be constrained with a precision of few % while looking at (anti-)ν_mu/tau. The innovative experimental approac |

| Exotic matter in neutron stars |
| Speaker: | Veronica Dexheimer (Kent State University) |
| Abstract: | The high densities achieved in neutron stars and the high densities and temperatures achieved in neutron-star mergers create ideal testing grounds in which to learn about exotic matter, namely hyperons and deconfined quarks. The presence of exotic matter can strongly affect the interior of neutron stars, but cannot be directly observed. New electromagnetic and gravitational-wave constraints have been slowly constraining the dense QCD equation of state, allowing us to learn important information about the strong interaction. Nevertheless, strong constraints on dense and hot matter depend on (a) the not yet observed post-merger period of gravitational-wave production from neutron-star mergers and (b) non-trivial comparisons with particle collision experimental data. In this talk, I discuss where we stand and what we expect to learn about dense matter in the near future. |
