This discovery is of great interest, because there is no particle in minimal SU(3) X SU(2) X U(1) with the properties of the ~'. The only candidate with the correct quantum numbers is the physical Higgs scalar, but its coupling to the b is too small for it to be produced at the observed rate. One is therefore motivated to consider an extended Higgs sector. A small vacuum expectation value (VEV) for one of the scalar fields can account for the enhanced rate. Since this field must couple to b quarks, it must be an SU(2) doublet. The other scalar(s), which have large VEVs to account for the W and Z masses, must then be doublets because P is close to one. We will consider the simplest such model, where there is one additional doublet \[2\]. There are then two charged scalars, two neutral 0 + scalars and a neutral pseudoscalar in the theory after symmetry breaking. The 0 + scalar associated with the small VEV can be light. The neutral pseudoscalar can be, but need not be light. The remaining particles are typically heavy, with masses/>100 GeV.

N2 - We consider the possibility that a two Higgs-doublet extension of the standard model can explain the ζ(8.3). If the ζ is a 0+, a renormalisation group analysis shows that the charge 2 3 and -1 3 quarks must couple to different doublets, and a fourth generation is excluded.
