Scientific paper

Present bounds on double beta decay and tritium decay together with cosmological bounds on early nucleosynthesis lead to stringent limits on both left-handed (mL) and right-handed (mR) Majorana masses: (mL + mR) ≲ 2× 10-10 eV. Therefore right-handed neutrinos of masses of a few keV are no longer a plausible candidate for galaxy formation processes.
