Tritium $\beta$-Energy Spectrum Analysis in Project 8 Phase II
ORAL
Abstract
The Project 8 experiment aims to determine the absolute neutrino mass scale by searching for a distortion to the tritium $\beta$-energy spectrum near the endpoint using the Cyclotron Radiation Emission Spectroscopy (CRES) technique. The first molecular tritium $\beta$-energy spectrum using CRES has been observed in Phase II of Project 8, from which the endpoint energy has been extracted. This talk presents the data analysis of the tritium $\beta$-energy spectrum to produce the final result of the Phase II endpoint measurement, with a focus on systematic effects.
