We develop the formalism for calculating the decay rate of neutrinoless double beta decay to the 2 + excited states within L-R symmetric model. We consider the eﬀects from induced hadronic currents up to NLO. The QRPA method in a spherical basis is adopted for the nuclear many-body calculation and the corresponding nuclear matrix elements are given. Also, the phase space factors are obtained with numerical electron wave functions. Our results suggest that the nuclear matrix elements are nucleus…
