How would neutrons interact with magnetic monopoles?

Sorry for the confusion ... what I meant by 'composite bodies' was 'other than a (sad and lonely) particle'. To use an analogy; back when there was interest in isolated quarks, macroscopic objects (such as tiny Nb spheres, blobs of ink in an ink-jet) were examined to see if any had a fractional charge. So the second part of my question is something like 'has anyone looked for monopoles in macroscopic blobs of matter? if so, what limits did those experiments/search set (e.g. fewer than 1 monopole in 10^25 atoms of Ni, or 10^32 molecules of NaCl)?tavi_boada said:I don't understand your answer nerid. I took an exam yesterday. This question came up. I've searched the web and have found nothing. My fellow students all gave different answers. My calculations yielded that the scattering would be inversely proportional too the square of the sine of half the polar angle. The question also said we could consider the neutrons to be polarized in the direction of the incident beam. Any ideas?

vanesch said:Are these "gluon-magnetic" monopoles - with that I mean the gluon-field equivalence of an electromagnetic monopole, or are you talking about genuine electromagnetic monopoles ?
(in another way, are you talking about the A^n_mu fields of QCD, or about the A_mu field of QED)
cheers,
Patrick.
marlon said:So basically two of these monopoles (two dual quarks if you will) interact via the "colour"-magnetic field which is the dual of the colour-electric field. So i am talking about the FIRST kind of monopole that you mentioned. The monopole that arise as the dual of the geniune electric charged-particle (like the electron, so no colour-charge but electric-charge) is not used...at least not to my knowledge and certainly NOT in QCD or when describing quark-confinement...
The neutron has a magnetic moment.tavi_boada said:How would neutrons interact with magnetic monopoles?
Magnetic monopoles are hypothetical particles that have only one magnetic pole, either a north pole or a south pole. In contrast, regular magnets have both a north and south pole.
The detection of magnetic monopoles could provide evidence for the unification of the fundamental forces of nature, specifically electromagnetism and the strong and weak nuclear forces.
Magnetic monopoles are typically searched for using high energy particle accelerators. These experiments involve colliding particles at high speeds and observing the resulting particles for signs of monopole production.
No, magnetic monopoles have not been detected yet. However, there have been some potential sightings and experiments are ongoing to try to confirm their existence.
If magnetic monopoles are detected, it could have major implications for our understanding of the universe and could lead to advancements in technology, such as more efficient energy generation.
