Description
To accommodate new physics like the tiny neutrino masses and dark matter, the standard model gauge group can be extended by an extra U(1) or by constructing left-right symmetric models at higher energies. However, the gauge couplings in these beyond the standard model gauge groups can not be arbitrarily large and/or small. Assuming the new physics emerges at the few-TeV scale and requiring the couplings to be perturbative up to the GUT/Planck scale, we examine the lower and upper bounds on the beyond standard model gauge couplings in the U(1) and left-right models, and the implications for the searches of corresponding gauge bosons at current and future high-energy colliders.
