In this work, we explore the possibility of TeV-scale leptogenesis within two realizations of the SDDM setup: Majorana SDDM scenario and Dirac SDDM scenario. The light neutrino mass, in either case, arises radiatively at one loop level. The particles running in the loop are…","published":"2026-09-29T04:00:00Z","seen":"2026-09-29T07:46:41Z","lang":"en","source":{"id":"arxiv-astro-ph","name":"arXiv astro-ph (astrophysics)","domain":"arxiv.org","outlet":{"wikidata":"Q118398","name":"arXiv","type":"website","country":"US","designations":["bibliographic database","disciplinary repository","online database","open science tool","preprint server","website"]}},"via":"arxiv-astro-ph","topics":["space","astrophysics","hep-ph","astro-ph.co","hep-ex","hep-th"],"authors":["Partha Kumar Paul, Narendra Sahu, Shashwat Sharma"],"entities":[{"id":"Q79925","name":"dark matter","type":"other"},{"id":"Q2126","name":"neutrino","type":"other"},{"id":"Q843946","name":"Book of Jubilees","type":"event"}],"story":"st_wwgpe356t4okoc2q52fa","category":"science-technology","category_p":0.47999998927116394,"sentiment":"neutral","tone":-0.029999999329447746,"political":0.1899999976158142}]}
