Abstract: Electromagnetic, weak, and strong forces are described as gauge forces mediated by photon, W and Z bosons, and gluons. Electromagnetic and weak forces are unified in SU(2)xU(1) gauge theory. In the  standard model (SM) the gauge symmetry is spontaneously broken by the Higgs boson. In 2012 the Higgs boson with a mass 125 GeV was discovered at 8 TeV LHC. We point out the possibility that the discovered Higgs boson is a part of the extra-dimensional component of the gauge fields so that the gauge fields and Higgs field are unified. We show how signatures of extra dimensions can be seen at the upgraded 14 TeV LHC.
