Cosmic rays through the Higgs portal
Rainer Dick, Robert B. Mann, Kai E. Wunderle
We consider electroweak singlet dark matter with a mass comparable to the Higgs mass. The singlet is assumed to couple to standard matter through a perturbative coupling to the Hig…
Variation of the fine structure constant in QSO spectra from coherent dark matter oscillations
M. G. Barnett, R. Dick, K. E. Wunderle
We consider the problem of the evolution of the fine structure coefficient alpha under the assumption that the scalar field coupling to the Maxwell term satisfies the condition mt>…
Ultrahigh energy cosmic rays from dark matter annihilation
R. Dick, P. Blasi, E. W. Kolb
Annihilation of clumped superheavy dark matter provides an interesting explanation for the origin of ultrahigh energy cosmic rays. The predicted anisotropy signal provides a unique…
Ultra-High Energy Cosmic Rays: The Annihilation of Super-Heavy Relics
Pasquale Blasi, Rainer Dick, Edward W. Kolb
We investigate the possibility that ultra-high energy cosmic rays (UHECRs) originate from the annihilation of relic superheavy (SH) dark matter in the Galactic halo. In order to fi…
Ultra-high energy cosmic rays from annihilation of superheavy dark matter
Pasquale Blasi, Rainer Dick, Edward W. Kolb
We consider the possibility that ultra-high energy cosmic rays originate from the annihilation of relic superheavy dark-matter particles. We find that a cross section of <sigma_A v…
