Cosmological Production of Superheavy Magnetic Monopoles
There has been much interest recently in grand unified models of elementary particle interactions, ' in which a simple gauge group breaks down at a @cry large mass scale to a group containing the SU(3)SSU(2)U(1) of the strong, weak, and electromagnetic interactions. Because the unbroken symmetry group contains a U(1) factor, general arguments' imply that such models contain topologically stable...
متن کاملSuppression of Superheavy Magnetic Monopoles in Grand Unified Theories
The superheavy magnetic monopoles predicted by grand unified theories would not be produced in significant numbers if electromagnetic gauge invariance is spontaneously broken when the temperature T is greater than T, 2 1 TeV. Grand unified theories predict the existence of superheavy magnetic monopoles.1-7 These monopoles are of the type discovered by 't Hooft and Polyakov.6 They exist if a sem...
متن کاملMulti-monopoles, Magnetic Bags, BIons and the Monopole Cosmological Problem
By analogy with the multi-vortices, we show that also moltimonopoles become magnetic bags in the large n limit. This drastic simplification allows us to compute the spectrum and the profile functions by means of classical stabilization arguments. We consider in detail the case of the BPS magnetic bag and we find their moduli space. We then consider the possibility of cosmological production of ...
متن کاملNew Limits on the Production of Magnetic Monopoles at Fermilab
First results from an experiment (Fermilab E882) searching for magnetically charged particles bound to elements from the CDF and DØ detectors are reported. The experiment is described, and limits on magnetic monopole pair production cross sections for magnetic charges 1, 2, 3, and 6 times the Dirac pole strength are presented. These limits (∼ 1 pb), hundreds of times smaller than those found in...
متن کاملImproved experimental limits on the production of magnetic monopoles.
We present new limits on low mass accelerator-produced pointlike Dirac magnetic monopoles trapped and bound in matter surrounding the D0 collision region of the Tevatron at Fermilab (experiment E-882). In the context of a Drell-Yan mechanism, we obtain cross section limits for the production of monopoles with magnetic charge values of 1, 2, 3, and 6 times the minimum Dirac charge of the order o...
