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…
Collider Searches for Heavy Neutral Leptons: beyond simplified scenarios
Asmaa Abada, Pablo Escribano, Xabier Marcano +1
With very few exceptions, the large amount of available experimental bounds on heavy neutral leptons - HNL - have been derived relying on the assumption of the existence of a singl…
Indirect constraints on lepton-flavour-violating quarkonium decays
Lorenzo Calibbi, Tong Li, Xabier Marcano +1
Within an effective-field-theory framework, we present a model-independent analysis of the potential of discovering new physics by searching for lepton flavour violation in heavy q…
A method for approximating optimal statistical significances with machine-learned likelihoods
Ernesto Arganda, Xabier Marcano, Víctor Martín Lozano +4
Machine-learning techniques have become fundamental in high-energy physics and, for new physics searches, it is crucial to know their performance in terms of experimental sensitivi…
