The NuTeV Anomaly May be Evidence of Magnetic Monopoles!

Hello to all:
You may recall my recent paper http://arxiv.org/abs/hep-ph/0508257, Magnetic
Monopoles and Duality Symmetry Breaking in Maxwell's Electrodynamics,
discussed on sci.+. Among the results in this paper was a prediction of a
2.35 TeV mass for the vector boson that mediates magnetic monopole
interactions. One question on my mind has been whether there is any
lower-energy manifestation of magnetic monopoles that might already have
been observed in experiments on the order, say, of s = 100 GeV^2.
I just finished a careful calculation of cross-section enhancements at s =
M_Z^2. For e-bar e --> mu-bar mu, the magnetic monopole interaction
enhances the cross section by about 2% over what is expected for electroweak
theory absent this interaction. The neutrinos are the only particles which
do not have this enhancement, because they carry no electric or magnetic
charge.
If one were to try to explain this without considering magnetic monopoles,
it turns out one would need to adjust the weak mixing angle by about .003.
That is, the weak mixing angle for interactions of the charged fermions
would need to be about .003 smaller than that of the neutral neutrinos in
order to account for the cross-sectional enhancements which I have now found
are due to magnetic monopoles.
That is the same magnitude as the NuTeV anomaly, and the right direction
also!
I hope to have the details out the door in the next week or so.
Jay.
