Probing the heavy neutrino hypothesis
Xabier Marcano
There is a strong experimental program searching for massive sterile neutrinos. Here we focus on the heavy regime above the GeV scale, where their existence can be probed in either…
Bounds on lepton non-unitarity and heavy neutrino mixing
Mattias Blennow, Enrique Fernández-Martínez, Josu Hernández-García +3
We present an updated and improved global fit analysis of current flavor and electroweak precision observables to derive bounds on unitarity deviations of the leptonic mixing matri…
Lepton Flavor Violation from diphoton effective interactions
Fabiola Fortuna, Xabier Marcano, Marcela Marín +1
We consider charged lepton flavor violating transitions mediated by the diphoton effective interactions and explore which processes can probe them better. Our anal…
Indirect upper limits on from
Fabiola Fortuna, Alejandro Ibarra, Xabier Marcano +2
We perform an effective field theory analysis to correlate the charged lepton flavor violating processes and . Using the current upper bounds…
Heavy Neutral Leptons Beyond Simplified Scenarios
Gioacchino Piazza, Asmaa Abada, Pablo Escribano +1
Heavy neutral leptons (HNL) constitute the building blocks of several neutrino mass generation mechanisms. Experimental searches depend on their masses and mixings with the active…
HNL mass degeneracy: implications for low-scale seesaws, LNV at colliders and leptogenesis
Enrique Fernández-Martínez, Xabier Marcano, Daniel Naredo-Tuero
Low-scale seesaw variants protected by lepton number symmetry provide a natural explanation of the smallness of neutrino masses but, unlike their higher-scale counterparts, with po…
