Bristol: Iop Publishing Ltd, n. 10, 30 p., 2013.1475-7516http://hdl.handle.net/11449/113059We study in detail the conditions to generate the baryon asymmetry of the universe from the annihilation of dark matter. This scenario requires a low energy mechanism for thermal baryogenesis, hence we first discuss some of these mechanisms together with the specific constraints due to the connection with the dark matter sector. Then we show that, contrary to what stated in previous studies, it is possible to generate the cosmological asymmetry without adding a light sterile dark sector, both in models with violation and with conservation of B - L. In addition, one of the models we propose yields some connection to neutrino masses.30engdark matter theorybaryon asymmetryleptogenesisOn baryogenesis from dark matter annihilationArtigo10.1088/1475-7516/2013/10/035WOS:000326979500035Acesso restrito
