Master Majorana neutrino mass parametrization
Isabel Cordero-Carrión, Martin Hirsch, Avelino Vicente
After introducing a master formula for the Majorana neutrino mass matrix we present a master parametrization for the Yukawa matrices automatically in agreement with neutrino oscill…
Long-Lived Fermions at AL3X
Daniel Dercks, Herbert K. Dreiner, Martin Hirsch +1
Recently Gligorov [arXiv:1810.03636] proposed to build a cylindrical detector named '' close to the experiment at interaction poin…
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…
High-dimensional neutrino masses
G. Anamiati, Oscar Castillo-Felisola, Renato M. Fonseca +2
For Majorana neutrino masses the lowest dimensional operator possible is the Weinberg operator at . Here we discuss the possibility that neutrino masses originate from higher…
Displaced vertices as probes of sterile neutrino mixing at the LHC
Giovanna Cottin, Juan Carlos Helo, Martin Hirsch
We investigate the reach at the LHC to probe light sterile neutrinos with displaced vertices. We focus on sterile neutrinos with masses (5-30) GeV, that are produ…
