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…
processes
Renato M. Fonseca, Martin Hirsch
We discuss the experimental prospects for observing processes which violate lepton number () in four units (or more). First, we reconsider neutrinoless quadruple beta decay, de…
processes: Proton decay and LHC
Renato M. Fonseca, Martin Hirsch, Rahul Srivastava
We discuss lepton number violation in three units. From an effective field theory point of view, processes can only arise from dimension 9 or higher operators. These operato…
