Abstract
Searches for the SM Higgs boson by the four LEP experiments have found a 2.3σ excess at 98 GeV and a smaller 1.7σ at around 115 GeV. We interpret these excesses as evidence for a Higgs boson coupled to a higher-dimensional singlet scalar. The fit implies a relatively low-dimensional mixing scale μlhd<50GeV, which explains the low confidence level found for the background fit in the range s1/2>100GeV. The data show a slight preference for a five-dimensional over a six-dimensional field. This Higgs boson cannot be seen at the LHC, but can be studied at the ILC.
