THE POSSIBILITY OF ξ(2.22) BEING THE STANDARD HIGGS BOSON

  • We discuss the possibility that the new particle ξ(2.22) is a mixed state of the Higgs boson of the minimal electro-weak model and the p-wave charmonium χ(3.415). If this possibility stands, we shall have Γξ=1.1 keV, Br(ξ→K+K)~1/5 and a heavy quark (m>75GeV).

Abstract: We discuss the possibility that the new particle ξ(2.22) is a mixed state of the Higgs boson of the minimal electro-weak model and the p-wave charmonium χ(3.415). If this possibility stands, we shall have Γξ=1.1 keV, Br(ξ→K+K)~1/5 and a heavy quark (m>75GeV).
