Hidden Dirac Monopoles
نویسنده
چکیده
Dirac showed that the existence of one magnetic pole in the universe could offer an explanation of the discrete nature of the electric charge. Magnetic poles appear naturally in most grand unified theories. Their discovery would be of greatest importance for particle physics and cosmology. The intense experimental search carried thus far has not met with success. I proposed a universe with magnetic poles which are not observed free because they hide in deeply bound monopole–anti-monopole states named monopolium. I discuss the realization of this proposal and its consistency with known cosmological features. I furthermore analyze its implications and the experimental signatures that confirm the scenario.

Minicharges, Monopoles, and Magnetic Mixing
Minicharged particles (MCPs) arise naturally in extensions of the Standard Model with hidden sector gauge groups. Many such extensions also contain magnetic monopoles. For models containing both monopoles and MCPs, we clarify the role of the Dirac charge quantization condition in restricting the possible charges. We also show that monopoles of the hidden sector may manifest themselves as MCPs, ...
متن کاملTopology of a Nontopological Magnetic Monopole
Certain nontopological magnetic monopoles, recently found by Lee and Weinberg, are reinterpreted as topological solitons of a non-Abelian gauged Higgs model. Our study makes the nature of the Lee-Weinberg monopoles more transparent, especially with regard to their singularity structure.

متن کامل0 Dirac Strings and Monopoles in the Continuum Limit of SU ( 2 ) Lattice Gauge Theory
Magnetic monopoles are known to emerge as leading non-perturbative fluctuations in the lattice version of non-Abelian gauge theories in some gauges. In terms of the Dirac quantization condition, these monopoles have magnetic charge |QM | = 2. Also, magnetic monopoles with |QM | = 1 can be introduced on the lattice via the ’t Hooft loop operator. We consider the |QM | = 1, 2 monopoles in the con...
متن کاملOn Explicit Point Multi-Monopoles in SU(2) Gauge Theory
It is well known that the Dirac monopole solution with the U(1) gauge group embedded into the group SU(2) is equivalent to the SU(2) Wu-Yang point monopole solution having no Dirac string singularity. We consider a multi-center configuration of m Dirac monopoles and n antimonopoles and its embedding into SU(2) gauge theory. Using geometric methods, we construct an explicit solution of the SU(2)...
متن کاملDirac and Yang monopoles revisited
The Dirac monopoles in 3-space and their generalization by C. N. Yang to 5-space are observed to be just the Levi-Civita spin connection of the cylindrical Riemannian metric on the 3and 5dimensional punctured spaces. Their straightforward generalization to higher dimensions is also investigated.
متن کاملAbout Dirac monopoles
Dirac showed that the existence of one magnetic pole in the universe could offer an explanation of the discrete nature of the electric charge. This appealing property has motivated a large experimental effort thus far negative. We describe a scenario in which Dirac monopoles exist but are difficult to detect in isolation. We propose ways of looking to their signatures. Pacs: 14.80.Hv, 98.70.-f,...
