Abstract

We stress the point that massive neutrinos may be Majorana particles even if the effective mass of the neutrinoless double beta decay 〈m〉_ee vanishes. We show that current neutrino oscillation data do allow 〈m〉_ee=0 to hold, if the Majorana CP-violating phases lie in two specific regions. Strong constraints on the neutrino mass spectrum can then be obtained. A possible texture of the neutrino mass matrix is also illustrated under the 〈m〉_ee=0 condition.
