In this work, the contributions of the Left-Right symmetric model (LRSM) to the half-life of neutrinoless double beta decay (0νββ) were theoretically analyzed. The constraints in the parameter space associated with the new mechanisms ⟨λ⟩ and ⟨η⟩ were calculated according to four considered scenarios, given by the current and future experimental limits for 0νββ decay in Ge-76, Te-130 and Xe-130.
