Yet their absolute mass scale and the mass ordering (whether the lightest neutrino state is predominantly electron-, muon-, or tau-like) remain unknown. Determining these properties is a central goal of modern particle physics. A promising approach involves measuring the energy spectrum of electrons emitted in nuclear <img decoding=\"async\" style=\"display:inline; margin: 0; margin-right: 8px;\" src=\"https:\/\/cdn.journals.aps.org\/libs\/mathjax\/2.7.2\/fonts\/HTML-CSS\/TeX\/png\/Math\/Italic\/400\/03B2.png?V=2.7.2\"> decay, particularly from tritium: Because the neutrino carries away part of the decay energy, a nonzero neutrino mass slightly modifies the spectrum of emitted electrons. Precision experiments such as KATRIN have pushed this method to its limit, setting an upper bound of about 0.45 eV on the neutrino mass [1]. While KATRIN uses molecular tritium gas, new strategies aim to go further by embedding tritium in engineered materials.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>New density-functional-theory calculations describe the radioactive decay of tritium bound to graphene, offering a way to model experiments that could open cleaner windows onto neutrino mass.
