A Feynman–Kac formula for magnetic monopoles

The search for magnetic monopoles

Minicharges and Magnetic Monopoles

Minicharged particles arise naturally in extensions of the Standard Model with a kinetic mixing term between the ordinary electromagnetic U(1) and an extra “hidden sector” U(1). In this note we study the compatibility of these particles with the existence of magnetic monopoles. We find that angular momentum quantization allows only certain combinations of ordinary and hidden monopole charge. Us...

Are magnetic monopoles hadrons?

The charges of magnetic monopoles are constrained to a multiple of times the inverse of the elementary unit electric charge. In the standard model, quarks have fractional charge, raising the question of whether the basic magnetic monople unit is a multiple of or three times that. A simple lattice construction shows how a magnetic monopole of the lower strength is possible if it interacts with g...

SEARCH 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).

Search for Magnetic Monopoles Trapped in Matter.

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 ...
