Is the proposed neutralino of Supersymmetry a force carrier?
Dear Dr. Artuso, I have read that a leading candidate for “cold dark matter” in supersymmetry theory is the neutralino, a superpartner of the photon, Zo, and Higgs bosons. That would make it a fermion, I suppose. My question is: should this particle exist (to be discovered by the LHC team?) would it also be a force transmitter in the realm of superpartner physics? Cyrus A. Bryant 252Old Creamery Rd Williston, VT 05495 You are actually correct, the neutralino is a hypothetical electrically neutral particle, superpartner of the photon, Z-boson, and Higgs Boson. There are 4 neutralinos and the lightest one is one of the leading candidates for cold dark matter in several theories. They are fermions, although in some theories they are considered “Majorana fermions”, namely they can self-annihilate. Their production mechanism and coupling to other elements of the SUSY ensamble depend on the specific variant of supersymmetry that you may want to consider, but I believe that picturing them as
