One of the major challenges in nowadays particle physics and astrophysics is the determination of the absolute neutrino mass scale. The HOLMES experiment aims at exploiting the calorimetric approach to directly measure the neutrino mass through the kinematic measurement of the decay products of163Ho electron capture (EC). The high energy...

The HOLMES project aims to directly measure the electron neutrino mass using the electron capture decay (EC) of 163Ho down to the eV scale. It will perform a precise measurement of the end-point of the 163Ho calorimetric energy spectrum to search for the deformation caused by a finite electron neutrino mass. The choice of 163Ho as source is...

One of the most crucial challenges in today particle physics and cosmology is the determination of the neutrino absolute mass scale. Currently, the only model independent method to set a limit neutrino mass is the study of the nuclear beta spectrum end-point. Performing a calorimetric measurement of the end point of the Electron Capture decay...

The absolute neutrino mass is still an unknown parameter in the modern landscape of particle physics. The HOLMES experiment aims at exploiting the calorimetric approach to directly measure the neutrino mass through the kinematic measurement of the decay products of the weak process decay of 163Ho. This low energy decaying isotope, in fact,...

This work summarizes the current status of HOLMES, a calorimetric experiment for the direct neutrino mass measurement. The state-of-the-art in this field is represented by the KATRIN spectrometer that is under data-taking aiming at a sensitivity of 0.2 eV. HOLMES will prove the feasibility of the calorimetric approach, that is an alternative...

The assessment of the absolute mass scale is a crucial challenge in today's particle physics and cosmology. The only experimental method which can provide a modelindependent measurement is the investigation of endpoint distortion in beta/electron capture spectra. 163 Ho is a good choice thanks to its low electron capture Q value (about 2.8...
