Search for Ferromagnetically Trapped Magnetic Monopoles of Cosmic-Ray Origin

Abstract

Same SubgrauP, Ir haS the quantum numberS (sr, rs), P the quantum numbers (-'"-',), and for Ao one has (0,0). It then follows that the (Rom') system in this reaction is uniquely in an "I"=1 state, hence, that the reaction amplitude is purely antisymmetric under E'~~m'. But this means that the differential cross section must be symmetric under interchange of the K' and &' momentuxn vectors. (3) Similarly, consider the reaction y+p-+ PI *+Z++sr+. In the octet model of SU(3) one can define a subgroup" " '4 N. Cabibbo and R. Gatto, Nuovo Cirnento 21, 872 (1961). similar to the one discussed under (2). With respect to this subgroup, K+ and~+ belong to a common doublet L("I", "I,")= (-', ,-',) fOr Z+; (s,-',) fOr Ir+]; p haS the quantum numbers (-, ',-' ,), the 1385-MeV resonance F'I *, supposedly belonging to the representation ten, " has the quantum numbers (ss, rs), and the photon transforms like a scalar (0,0). Therefore, the (%+sr+) system in this reaction is in a pure "I"= 1 state, hence, the reaction amplitude is symmetric under K+~&+.

Non-collider searches for stable massive particles

“…The acceleration of monopoles in galactic magnetic fields is a well studied subject [140][141][142].…”

“…In Ref. [140] it is pointed out that a binding to nuclei would not affect the results of searches with the extraction technique because, for the sample thicknesses considered in this search, the magnetic field would be strong enough to extract the whole atom or even clusters of atoms from the material surface. However, this claim has been questioned on the basis that monopoles bound to nuclei would remain stuck if there is no available nearby site for the atom to jump to in a solid lattice [258].…”

“…The device on the left was designed to be portable to be carried to a site where it can scan rock outcrops (Figure from Ref. [140]). The device on the right was designed for samples from the Fermilab accelerator and was also used in a search for monopoles trapped in air and seawater (Figure from ref.…”

Search for Magnetic Monopoles in the Moon

“…Goto et al (14) reported a flux less than 10 -13/cm2 sec or a mass greater than 10 Gev to escape detection. The high field of a pulsed magnet was used to extract magnetic monopoles should they exist in a magnetic outcrop on the earth's surface and from fragments of a stony iron meteorite.…”

“…Malkus (8) first searched for the elusive magnetic particle (14), and Katz and Butts (15). Goto et al (14) reported a flux less than 10 -13/cm2 sec or a mass greater than 10 Gev to escape detection.…”
