Description
The effective Lagrangian for tritium β decay in the Standard Model can be extended by introducing additional Lorentz-invariant coupling terms analogous to those of the electroweak interaction. This framework, known as Generalized Neutrino Interactions (GNIs), incorporates interactions involving light and heavy neutrinos as well as right- and left-handed neutrino currents coupled to quarks and leptons. We measure the tritium β-decay spectrum using a LiF crystal coupled to a cryogenic metallic magnetic calorimeter (MMC) over a four-month data-taking period. This presentation reports the analysis results constraining the GNI coupling constants based on a 10-day subset of the full four-month data set.
