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...

description 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 production with respect to that calculated by assuming that the resonant peak indicates the SM Higgs. If the radion is highly degenerate in mass with the Higgs, the cross section can be increased more than at one sigma level. The implications of the radion effects on the preliminary ALEPH data are also discussed.
