Gauge bosons associated with unbroken gauge symmetries, under which all standard model fields are singlets, may interact with ordinary matter via higher-dimensional operators. A complete set of dimension-six operators involving a massless U(1) field, {gamma}', and standard model fields is presented. The {mu} {yields} e{gamma}' decay, primordial nucleosynthesis, star cooling and other phenomena set lower limits on the scale of chirality-flip operators in the 1-15 TeV range, if the operators have coefficients given by the corresponding Yukawa couplings. Simple renormalizable models induce {gamma}' interactions with leptons or quarks at two loops, and may provide a cold dark matter candidate.
