Neutrino: chronicles of an aloof protagonist
Alejandra Melfo, Goran Senjanovic
We give a brief account of the history of neutrino, and how that most aloof of all particles has shaped our search for a theory of fundamental interactions ever since it was theore…
A note on Spontaneous Symmetry Breaking in flocks of birds
Alejandra Melfo
It is suggested that the observed scale-free correlations of speed fluctuations in flocks of birds are a consequence of the spontaneous breakdown of translational symmetry to a dis…
Type II Seesaw at LHC: the Roadmap
Alejandra Melfo, Miha Nemevsek, Fabrizio Nesti +2
In this Letter we revisit the type-II seesaw mechanism based on the addition of a weak triplet scalar to the standard model. We perform a comprehensive study of its phenomenology a…
Inert Doublet Dark Matter and Mirror/Extra Families after Xenon100
Alejandra Melfo, Miha Nemevsek, Fabrizio Nesti +2
It was shown recently that mirror fermions, naturally present in a number of directions for new physics, seem to require an inert scalar doublet in order to pass the electroweak pr…
Self-gravitating non-abelian kinks as brane worlds
Alejandra Melfo, Roger Naranjo, Nelson Pantoja +2
We address the properties of self-gravitating domain walls arising from the breaking of an SU(N) x Z_2- symmetric theory. In the particular case of N=5, we find that the two classe…
Three Extra Mirror or Sequential Families: a Case for Heavy Higgs and Inert Doublet
Homero Martínez, Alejandra Melfo, Fabrizio Nesti +1
We study the possibility of the existence of extra fermion families and an extra Higgs doublet. We find that requiring the extra Higgs doublet to be inert leaves space for three ex…
