2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/214147We explore a new origin of neutrino dark energy and baryon asymmetry in the universe. The neutrinos acquire small masses through the Dirac seesaw mechanism. The pseudo-Nambu-Goldstone boson associated with neutrino mass-generation provides a candidate for dark energy. The puzzle of cosmological baryon asymmetry is resolved via neutrinogenesis.6 pages, 1 figure. Accepted by JCAP (only minor rewordings, refs added)High Energy Physics - Phenomenologytext
