Radion effects on the production of an intermediate-mass scalar and Z at LEP II
We have studied the $ e^+ e^- \to Z \phi_i \to Z b\bar{b}$ process, where $\phi_i$ is the Higgs and/or radion bosons. In the case where the radion is lighter than the Higgs, the enhanced coupling between the radion and two gluons due to the trace anomaly suppresses the cross section of radion produc...
