Right-handed weak currents in neutrinoless ${\hat{I}}^2{\hat{I}}^2$ decays and ton scale ${\hat{I}}^2{\hat{I}}^2$ detectors

Right handed weak-currents (RHCs) in the left-right (L-R) symmetric model for neutrinoless double beta decays (DBDs) of both the $0^{+}\to 0^{+}$ and $0^{+}\to 2^{+}$ transitions are dis…
