Limits on a light leptophobic gauge boson

We consider the phenomenology of a naturally leptophobic Z-prime boson in t he 1 to 10 GeV mass range, The Z-prime's couplings to leptons arise only vi a a radiatively-generated kinetic mixing with the Z and photon, and hence a re suppressed. We map out the allowed regions of the mass-coupling plane an d show that such a Z-prime that couples to quarks with electromagnetic stre ngth is not excluded by the current data. We then discuss possible signatur es at bottom and charm factories. (C) 1998 Elsevier Science B.V. All rights reserved.
