| dc.description | We study thermal leptogenesis from decays of the electroweak triplets that mediate neutrino masses in type-II and type-III see-saw. We find that Sommerfeld corrections reduce the baryon asymmetry by ~30%, and that successful leptogenesis needs triplets heavier than 1.6 TeV, beyond the discovery reach of LHC. | |
| dc.description | 12 pages, 4 figures, final version. The group theory of the non-abelian Sommerfeld effect presented in this paper can be relevant for scenarios of Dark Matter charged under new dark gauge groups, as suggested by recent data | |
