HOLMES is an experiment aiming at performing a direct measurement of the neutrino mass from the electron capture (EC) spectrum of 163Ho. In order to reach a sensitivity of the order of ∼ 1 eV/c2 on the neutrino mass, it is necessary to gather as many as 10 13 events in the 3-year projected live time of HOLMES, keeping the pileup fraction as low...

The neutrino mass is a fundamental parameter of the Standard Model and the measurement of its value is one of the most compelling issues in particle physics. HOLMES is an experiment set up at the University of Milano-Bicocca aiming at performing a direct measurement of the neutrino mass from the Electron Capture (EC) decay of 163Ho. HOLMES will...

Sudden unexpected death in epilepsy is an unpredicted condition in patients with a diagnosis of epilepsy, and autopsy does not conclusively identify cause of death. Although the pathophysiological mechanisms that underlie this entity remain unknown, the fact that epilepsy can affect cardiac function is not surprising. The genetic factors...

We present the first performance results obtained with microwave multiplexed Transition Edge Sensors prototypes specifically designed for the HOLMES experiment, a project aimed at directly measuring the electron neutrino mass through the calorimetric measurement of the 163 Ho electron capture spectrum. The detectors required for such an...

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 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...

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...
