QCD contributions to the thermal history of the early Universe
Jose A. R. Cembranos
We discuss the deviations from the ideal relativistic thermal bath. These deviations are dominated from quantum chromodynamic (QCD) corrections in the most part of the parameter sp…
Fitting formulae for photon spectra from WIMP annihilation
J. A. R. Cembranos, A. de la Cruz-Dombriz, A. Dobado +2
Annihilation of different dark matter (DM) candidates into Standard Model (SM) particles could be detected through their contribution to the gamma ray fluxes that are measured on t…
Photon spectra from quark generation by WIMPs
J. A. R. Cembranos, A. de la Cruz-Dombriz, A. Dobado +2
In this work we provide the fitting formula valid for the simulated photon spectra from WIMP annihilation into light quark-anti quark (qq-) channels in a wide range of WIMP masses.…
Photon spectra from WIMP annihilation
J. A. R. Cembranos, A. de la Cruz-Dombriz, A. Dobado +2
If the present dark matter in the Universe annihilates into Standard Model particles, it must contribute to the fluxes of cosmic rays that are detected on the Earth, and in particu…
Dark Matter from R^2-gravity
Jose A. R. Cembranos
The modification of Einstein gravity at high energies is mandatory from a quantum approach. In this work, we point out that this modification will necessarily introduce new degrees…
Gravitino and Axino SuperWIMPs
J. A. R. Cembranos, Jonathan L. Feng, A. Rajaraman +1
Gravitinos and axinos produced in the late decays of other supersymmetric particles are well-motivated dark matter (DM) candidates, whose experimental evidences are very distinctiv…
