Physics Opportunities Beyond the Neutrino Mass Measurement with Project 8

The Project 8 experiment is designed to directly measure the electron-weighted neutrino mass using the novel technique called Cyclotron Radiation Emission Spectroscopy (CRES). Using the cyclotron frequency of the beta decay electrons as a proxy for kinetic energy, the experiment aims to measure the endpoint spectrum of tritium beta-decay electrons trapped in a uniform magnetic field to reach a mass sensitivity of 40 meV/c². The use of CRES technique by Project 8 enables a simultaneous measurement of the β spectrum both above and below the endpoint and provides an opportunity to perform standard model measurements and beyond standard model searches in addition to the neutrino mass measurement with Project 8. This talk will outline the additional physics capabilities of Project 8 experiment including the determination of neutrino mass ordering, search for light sterile neutrinos, and search for cosmic neutrino background.
