ABSTRACT: The existence of neutrinoless double-beta decay is one of the most important questions in physics beyond the standard model today. If neutrinoless double-beta decay is unambiguously observed one can probe physics beyond the electroweak scale and obtain measurements of the absolute neutrino mass scale. Since double-beta decay searches favor heavy elements where beta decay is forbidden, the calculated decay rate is proportional to complicated nuclear matrix elements in addition to a measure of the absolute neutrino mass scale.
Historically, the matrix elements are a large source of error. The talk will discuss some ongoing measurements whose goal is to reduce the error in these matrix elements and make the accurate measurement of an absolute neutrino mass scale attainable
