Z → b b in a composite model of fermions
Hung, P. Q.
Original · EN
A composite model of fermions is proposed to explain the "anomaly" in Z → b b and, to a lesser extent, in Z → c c. It contains a nonsequential fourth family whose mass of one member (the charge -1/3 quark) is constrained to be between 47 GeV and 49 GeV. The charge +2/3 quark is constrained to lie between 67 GeV and 107 GeV. This opens up the exciting prospect for near-future discoveries at LEP2 and possibly at the Tevatron.
