Recently a lot of progress has been made towards a full classification of newphysics effects in Higgs observables by means of effective dimension sixoperators. Specifically, Higgs production in association with a high transversemomentum jet has been suggested as a way to discriminate between operators thatmodify the Higgs-top coupling and operators that induce an effectiveHiggs-gluon coupling---a distinction that is hard to achieve with signalstrength measurements alone. With this article we would like to draw attentionto another source of new physics in Higgs+jet observables: the triple gluonoperator $O_{3g}$ (consisting of three factors of the gluon field strengthtensor). We compute the distortions of kinematic distributions in Higgs+jetproduction at a 14 TeV LHC due to $O_{3g}$ and compare them with thedistortions due to dimension six operators involving the Higgs doublet. We findthat the transverse momentum, the jet rapidity and the difference between theHiggs and jet rapidity are well suited to distinguish between the contributionsfrom $O_{3g}$ and those from other operators, and that the size of thedistortions are similar if the Wilson coefficients are of the same order as theexpected bounds from other observables. We conclude that a full analysis of newphysics in Higgs+jet observables must take the contributions from $O_{3g}$ intoaccount.
