Abstrakt:
The Karlsruhe Tritium Neutrino (KATRIN) experiment aims to make a precision measurement of the effective neutrino mass by leveraging the kinematics of tritium beta decay, with a 3-year sensitivity of 0.2eV (90% C.L.). Recent run campaigns, both in standard mode (using molecular tritium) and calibration mode (using 83mKr), have provided a wealth of data. This data was analyzed using the CMKAT analysis framework, which models the integrated spectra using a convolution of the source decay physics and the experiment’s response function. Results from fits to the second neutrino mass measurement campaign (KNM2) are presented, and confidence intervals on the extracted effective neutrino mass are constructed. Finally, the physics reach of the KATRIN experiment is put into context by comparison to a successor neutrino experiment, Project8, which is currently under construction.
