Description

Determining the absolute neutrino mass scale remains a central challenge in cosmology and particle physics. The PTOLEMY experiment is designed to address this through precision spectroscopy of tritium beta decay. We will outline the experimental concept, focusing on two key innovations: a high-purity tritium target bound to graphene, and a novel, compact electromagnetic filter that reduces the kinetic energy of beta electrons for high-resolution measurement. We will discuss the projected sensitivity to sub-eV neutrino masses and the implications for cosmology and particle physics.
