Natural explanation for 130 GeV photon line within vector boson dark matter model
Yasaman Farzan, Amin Rezaei Akbarieh
We present a dark matter model for explaining the observed 130 GeV photon line from the galaxy center. The dark matter candidate is a vector boson of mass with a dimensionles…
Implications of the Pseudo-Dirac Scenario for Ultra High Energy Neutrinos from GRBs
Arman Esmaili, Yasaman Farzan
The source of Ultra High Energy Cosmic Rays (UHECR) is still an unresolved mystery. Up until recently, sources of Gamma Ray Bursts (GRBs) had been considered as a suitable source f…
Recipes and Ingredients for Neutrino Mass at Loop Level
Yasaman Farzan, Silvia Pascoli, Michael A. Schmidt
The large hierarchy between the neutrino mass scale and that of the other fermions seems to be unnatural from a theoretical point of view. Various strategies have been devised in o…
VDM: A model for Vector Dark Matter
Yasaman Farzan, Amin Rezaei Akbarieh
We construct a model based on a new gauge symmetry and a discrete symmetry under which the new gauge boson is odd. The model contains new complex scalars which carry…
Dirac neutrino mass generation from dark matter
Yasaman Farzan, Ernest Ma
In 2006, a simple extension of the Standard Model was proposed in which neutrinos obtain radiative Majorana masses at one-loop level from their couplings with dark matter, hence th…
Proceedings of the first workshop on Flavor Symmetries and consequences in Accelerators and Cosmology (FLASY2011)
M. Hirsch, D. Meloni, S. Morisi +43
The main goals of the first "Workshop on FLAvor SYmmetries and consequences in accelerators and cosmology" (FLASY) was to summarize the theoretical status of flavor symmetries, bri…
