2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/186292We present a TeV scale model for leptogenesis where the origin of neutrino masses are independent of the scale of leptogenesis. As a result, the model could be extended to explain {\it dark matter, neutrino masses and leptogenesis at the TeV scale}. The most attractive feature of this model is that it predicts a few hundred GeV triplet Higgs scalar that can be tested at LHC or ILC.4 pages, contribution to International workshop on theoretical high energy physics (IWTHEP), Roorkee, 2007High Energy Physics - Phenomenologytext
