Abstract: In the context of the minimal left-right symmetric model, we study the interplay between current and future neutrinoless double beta (0νββ) decay experiments, long-lived particle searches at the LHC main detectors ATLAS/CMS, and the proposed far detector MATHUSLA. The heavy Majorana neutrino can be produced in association with an electron from the decay of W boson for a non- zero left-right mixing and subsequently decays into another electron with the same charge and jets. Owing to the suppression of large right-handed charged gauge boson WR mass, the heavy neutrinos could be long-lived. We show that long-lived particle (LLP) searches for heavy Majorana neutrinos in the same-sign dilepton channel at the LHC can be used to extend WR boson mass reach relative to the reach of the Keung-Senjanovic (KS) process.
