Search for Magnetic Monopoles Trapped in Matter.

چکیده
There have been many searches for magnetic monopoles in ight, but few for monopoles in matter. We have searched for magnetic monopoles in meteorites, schists, ferromanganese nodules, iron ores and other materials. The detector was a superconducting induction coil connected to a SQUID (Superconducting Quantum Interference Device) with a room temperature bore 15 cm in diameter. We tested a total of more than 331 kg of material including 112 kg of meteorites. We found no monopole and conclude the overall monopole/nucleon ratio in the samples is < 1:2 10 29 with a 90% con dence

Joseph L. Kirschvink* Division of Geological and Planetary Sciences, The California Institute of Technology, Pasadena, California 91125 (Received 5 August 1985) Current experimental limits on the number of magnetic monopoles bound in matter are based on only a few dozen kilograms of material, and of the former experiments only a handful used superconducting-quantum-interference-device(SQUID) ba...
متن کاملTesting Abelian dyon - fermion Bound System
Characteristics of Abelian dyon fermion bound system, parity violating effects, a new series of energy spectra, effects related to the non vanishing electric dipole moment, feature of spin orientation etc, are analyzed and compared with hydrogen like atom. These analyses explore possibility of a new approach of searching for dyons under bound condition. § E-mail address: [email protected]...
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...
متن کاملSEARCH FOR “ LIGHT ” MAGNETIC MONOPOLES The SLIM
We propose to implement one passive nuclear track detector array of 400 m at the Chacaltaya High Altitude Laboratory (5230 m a.s.l.). The main purposes of the experiment concern the searches for magnetic monopoles of relatively low masses at the Parker bound level, searches for low mass nuclearites, and searches for some supersymmetric dark matter candidates (Q-balls).
متن کاملMagnetic Monopole Searches
“At the present time (1975) there is no experimental evidence for the existence of magnetic charges or monopoles, but chiefly because of an early, brilliant theoretical argument by Dirac, the search for monopoles is renewed whenever a new energy region is opened up in high energy physics or a new source of matter, such as rocks from the moon, becomes available [1]. ” Dirac argued that a monopol...
