Description
The neutrino has a lifetime that is significantly longer than the Age of the Universe as it can only decay radiatively via loops with gauge bosons. However the presence of physics Beyond the Standard Model could induce 'visible' neutrino decay between neutrino mass eigenstates. This decay process could be identified in laboratory experiments as well as from astrophysical or cosmological observations. To study neutrino systems that involve both oscillation and decay two main formalisms have been developed---a density matrix approach and a phenomenological approach. In this work we present an analysis of both highlighting the physical effects captured by each framework.
