Effect of TeV scale new physics on the cross-section for the process e+e−→Hγ

TeV scale new heavy physics could significantly affect the cross-section for the rare process e+e−→Hγ through non-renormalizable operators involving the light SM fields. In this article we show that for s=500 GeV and Λ=1 TeV some of these operators, which are only weakly constrained by the latest LEP and SLD data, could produce an observable number of events for mH lying in the range 200–500 GeV. Whereas for Λ=5 TeV although no event with mH≤250 GeV is likely to be seen, for moderately heavy higgs bosons with mH lying in the range (400–500) GeV the production rate will be large enough to be detectable.
