Abstract: In a class of the gauge–Higgs unification models the 4D neutral Higgs boson, which is a part of the extra-dimensional component of the gauge fields, becomes absolutely stable as a consequence of the gauge invariance and dynamically generated new parity, serving as a promising candidate for cold dark matter (CDM). We show that the observed relic abundance of cold dark matter is obtained in the model in the warped space with the Higgs mass around 70 GeV. The Higgs–nucleon scattering cross section is found to be close to the current CDMS II and XENON10 bounds in the direct detection of dark matter. [Copyright &y& Elsevier] |
