摘要：

We examine the charged lepton flavor violating process gg -> mu(+/-)tau(-/+) at the root s = 13 TeV LHC. Operators generating this process can be induced by new physics (NP) at dimension 8. Despite the power suppression associated with dimension 8 operators, we show that the LHC's large gluon luminosity makes it possible to probe this channel. For an integrated luminosity of 100 fb(-1) at the LHC, we predict a constraint on the NP scale Lambda greater than or similar to 3 TeV. In addition, we point out that such operators can be induced through top quark loops in models that generate dimension 6 operators of the form (t) over bart mu tau. We find that the NP scale of these dimension 6 operators can be constrained to be Lambda greater than or similar to 3.4-4.1 TeV with 100 fb(-1) of data. Published by Elsevier B.V.
