NuMass 2024 - Determination of the absolute electron (anti)-neutrino mass

Description

One of the major challenges in nowadays particle physics and astrophysics is the determination of the absolute neutrino mass scale. Its determination would answer one of the most important questions in physics.

https://www.nature.com/articles/d41586-024-00620-9

The KATRIN experiment, designed for the direct determination of the effective electron anti-neutrino mass, has recently set a sub-eV limit. New experiments with H-3, such as Project8 and PTOLEMY, and with Ho-163, such as ECHo and HOLMES, are completing the R&D phase with the publication of new data.

The goal of this international workshop is to better exploit the potential of current and future direct neutrino mass experiments and to provide a unique opportunity to discuss experimental details and theoretical implications in a synergistic setting.

The topics to be covered by workshop include the following:

  • Neutrino mass experimental overviews: neutrinoless double beta decay, cosmology, oscillations, sterile neutrinos, cosmic neutrino background...
  • Direct neutrino mass measurements: beta decay and electron capture (EC) end-point studies
  • Experimental aspects: detector technologies, read-out electronics, data acquisition...
  • Data analysis: signal processing, statistical data analysis, background studies, calibration methods, detector modeling...
  • Theoretical description of beta/EC spectra

This meeting will bring together the direct neutrino mass experiment community and experts from neutrino physics, astrophysics, and cosmology to critically assess the prospects for the measurement of the neutrino mass.

      A history of neutrino and its mass

      In this seminar, the history of the neutrino and its mass is recounted in six short chapters, with a bit of emphasis on the theoretical aspects:
      1. Pauli's proposal is presented, clarifying its significance and the context in which it arose, that of the earliest theories of the atomic nucleus.
      2. The first beta-ray theory, due to Enrico Fermi, is described, clarifying its potential but also its formal and conceptual limitations.
      3. Majorana's ideas, from which the modern treatment of neutrinos and fermions in general originated, are illustrated.
      4. Major advances in the next 30 years concern the existence of fermion families and the chiral structure of weak interactions, directly related to the hypothesis of neutrinos with zero mass.
      5. Conceptions on the mass of neutrinos and the main ways to probe them are then summarised.
      6. Prospects for development are briefly discussed in the last chapter of the story, which is the one yet to be written.
