Abstract:
The lecture is composed of two parts. In the first part, I will walk through the formula for the half-life of neutrinoless double-beta decay in atomic nuclei which is usually factorized into a product of phase-space factor, nuclear matrix element (NME), and new physics parameter. Taking the process of two neutrons decaying to two protons plus two electrons as an example, I will show the necessity and contribution of the recently proposed contact transition operator at the leading order in the chiral effective field theory for the neutrinoless double-beta decay. In the second part, I will introduce the main ideas of nuclear models that have been frequently employed to compute the NMEs of candidate neutrinoless double-beta decay and the recent achievements in this direction.
