Abstract
The sterile neutrino contribution to neutrinoless double beta (0νββ) decay has been first studied within a specific model with the two sterile neutrinos mixed only with the νe flavor state. In the present paper, we assume that in addition to the three conventional light neutrinos there exists only one Majorana neutrino mass-eigenstate νh, dominated by the sterile neutrino species, with an arbitrary mass mh, which may mix with all the active neutrino weak eigenstates νe,μ,τ. We study possible contribution of this νh neutrino state to 0νββ-decay via a nonzero admixture of νe weak eigenstate.

Keywords
