Dark matter stability and Dirac neutrinos using only Standard Model symmetries
Cesar Bonilla, Salvador Centelles Chuliá, Ricardo Cepedello +2
We provide a generic framework to obtain stable dark matter along with naturally small Dirac neutrino masses generated at the loop level. This is achieved through the spontaneous b…
Neutrinoless Double- Decay with Nonstandard Majoron Emission
Ricardo Cepedello, Frank F. Deppisch, Lorena González +2
We present a novel mode of neutrinoless double beta decay with emission of a light Majoron-like scalar particle phi. We assume it couples via an effective seven-dimensional operato…
Systematic classification of three-loop realizations of the Weinberg operator
Ricardo Cepedello, Renato M. Fonseca, Martin Hirsch
We study systematically the decomposition of the Weinberg operator at three-loop order. There are more than four thousand connected topologies. However, the vast majority of these…
