Super Heavy Dark Matter and UHECR Anisotropy at Low Energy

Super Heavy quasi-stable particles are naturally produced in the early universe and could represent a substantial fraction of the Dark Matter: the so-called Super Heavy Dark Matter (SHDM). The decay of SHDM represents also a possible source of Ultra High Energy Cosmic Rays (UHECR), with a reliably calculated spectrum of the particles produced in the decay (∝ E−1.9). The SHDM model for the produ...

Halo Dark Matter and Ultra-High Energy Cosmic Rays

The decay of very heavy metastable relics of the Early Universe can produce ultrahigh energy cosmic rays (UHECRs) in the halo of our own Galaxy. On distance scales of the order of the halo size, energy losses are negligible—no Greisen-ZatsepinKuzmin cutoff is expected. In this letter we show that, as a consequence of the hierarchical build up of the halo, this scenario predicts the existence of...

Hidden photons as Dark Matter

There is an asymmetry between the mass of the electric charges, for example proton and electron, can understood by the asymmetrical Planck Distribution Law. This temperature dependent energy distribution is asymmetric around the maximum intensity, where the annihilation of matter and antimatter is a high probability event. The asymmetric sides are creating different frequencies of electromagnet...

Hunting for dark matter with ultra-stable fibre as frequency delay system

Many cosmological observations point towards the existence of dark-matter(DM) particles and consider them as the main component of the matter content of the universe. The goal of revealing the nature of dark-matter has triggered the development of new, extremely sensitive detectors. It has been demonstrated that the frequencies and phases of optical clock have a transient shift during the DMs' ...

Dark matter with ultra compact mini halos

The isocurvature mode of dark matter is not damped away during kinetic decoupling from the thermal plasma. For weakly interaction massive particle as dark matter, the large density perturbation can generate the small scale ultra compact mini halos and the annihilation of dark matter inside them can give accessible signatures in the indirect detection of dark matter. The early matter domination ...
