Motivated by large nu(mu)-nu(tau) flavor mixing, we consider mu tau production at hadron colliders via dimension-6 effective operators, which can be attributed to new physics in the flavor sector at a higher scale Lambda. Current bounds on many of these operators from low energy experiments are very weak or nonexistent, and they may lead to clean mu(+)tau(-) and mu(-)tau(+) signals at hadron colliders. At the Tevatron with 8 fb(-1), one can exceed current bounds for most operators, with most 2 sigma sensitivities being in the 6-24 TeV range. We find that at the LHC with 1 fb(-1) (100 fb(-1)) integrated luminosity, one can reach a 2 sigma sensitivity for Lambda similar to 3-10 TeV (Lambda similar to 6-21 TeV), depending on the Lorentz structure of the operator. For some operators, an improvement of several orders of magnitude in sensitivity can be obtained with only a few tens of pb(-1) at the LHC.
