Darkly Charged ALPs
Nicolás M. Arenaza, Enrique Fernández-Martínez, Belén Gavela +4
The established ALP effective Lagrangian describes the interaction of scalars with approximate shift-symmetry which carry no Standard Model (SM) charges with SM fields. It im…
Gauged Flavour for Asymmetric Dark Matter
Mattias Blennow, Enrique Fernandez-Martinez, David Garcia-Garcia +1
We propose a framework that links the origin of the Standard Model flavour hierarchies to the generation of asymmetric dark matter via leptogenesis. The key new ingredient is a gau…
Leptogenesis and Dark Matter in an Inverse Seesaw from gauged B-L breaking
Enrique Fernández-Martínez, Ana Luisa Foguel, Xabier Marcano +3
We study a dynamical realization of the low-scale Inverse Seesaw mechanism in which the approximate symmetry is gauged and spontaneously broken. Anomaly cancellation requires…
Electroweak Baryogenesis
E. Fernandez-Martinez, J. Lopez-Pavon, T. Ota +1
We investigate if the CP violation necessary for successful electroweak baryogenesis may be sourced by the neutrino Yukawa couplings. In particular, we consider an electroweak scal…
