Neutrino fluxes from Dark Matter in the HESS J1745-290 source at the Galactic Center
J. A. R. Cembranos, V. Gammaldi, A. L. Maroto
The spectral study of the HESS J1745-290 high energy gamma-ray cut-off from the galactic center is compatible with a signal of Dark Matter (DM) annihilation or decay. If this is th…
Gamma-ray and neutrino fluxes from Heavy Dark Matter in the Galactic Center
V. Gammaldi, J. A. R. Cembranos, A. de la Cruz-Dombriz +2
We present a study of the Galactic Center region as a possible source of both secondary gamma-ray and neutrino fluxes from annihilating dark matter. We have studied the gamma-ray f…
Solution to the Isotropy Problem for Cosmological Hidden Vector Models
J. A. R. Cembranos, A. L. Maroto, S. J. Nunez Jareno
Gauge bosons associated to new gauge symmetries under which the standard model particles are not charged are predicted in many extensions of the standard model of particles and int…
Dark matter origin of the gamma ray emission from the galactic center observed by HESS
J. A. R. Cembranos, V. Gammaldi, A. L. Maroto
We show that the gamma ray spectrum observed with the HESS array of Cherenkov telescopes coming from the Galactic Center (GC) region and identified with the source HESS J1745-290,…
Branons as dark matter
J. A. R. Cembranos, A. Dobado, A. L. Maroto
In the brane-world scenario with low tension, brane fluctuations (branons) together with the Standard Model particles are the only relevant degrees of freedom at low energies. Bran…
Brane-skyrmions and wrapped states
J. A. R. Cembranos, A. Dobado, A. L. Maroto
In the context of a brane world and including an induced curvature term in the brane action, we obtain the effective lagrangian for the Goldstone bosons (branons) associated with t…
