fraction of monopoles bound to protons that they captured in the early universe. For all reasonable values of the monopole-proton binding energy (40 to 200 keV) and of the baryon to photon ratio (4 to ? x 10-1°), they concluded that essentially all monopoles are now bound to protons, and

(mmonopole > 2 GeV) [4]. For us here the monopole mass will be a parameter which we adjust to our wishful physical scenario. Let us assume that at some early stage in the expansion of the universe point-like Dirac monopoles and their antiparticles are created. Is it possible that at present

ATLAS experiment

ATLAS experiment 2 ATLAS is designed as a general-purpose detector. When the proton beams produced by the Large Hadron Collider interact in the center of the detector, a variety of different particles with a broad range of energies may be produced.

Hidden Dirac Monopoles arXiv:0709.0470v1 [astro-ph] 4 Sep 2007

At some early stage in the expansion of the Universe, monopoles and their an-tiparticles were created. At a later time the dynamics was such that most of the poles paired up to form monopole-anti-monopole bound states called monopolia. This happened because it is easier for the monopoles to interact with each other

dissociation halts the progress of the shock rendering it a standing accretion shock with a radius of 100 200 km about 50 ms after it is launched. In this accreting state, the inner regions of the star continue to collapse and pass through the shock. The shocked, still infalling matter is dissociated and much of it settles on the PNS.
