0+→2+ 0νββ decay triggered directly by the Majorana neutrino mass

We treat 0+→2+ 0νββ decays taking into account recoil corrections to the nuclear currents. The decay probability can be written as a quadratic form of the effective coupling constants of the right-handed leptonic currents and the effective neutrino mass. We calculate the nuclear matrix elements for the 0+→2+1 0νββ decays of 76Ge and 100Mo, and demonstrate that the relative sensitivities of 0+→2+ decays to the neutrino mass and the right-handed currents are comparable to those of 0+→0+ decays.
