Hadrophilic Z': and explanation of LEP1, SLC and CDF anomalies?

In order to explain possible departures from the Standard Model predictions of $b\overline{b}$ and $c\overline{c}$ production at Z peak, we propose the existence of a Z' vector boson with enhanced couplings to quarks. We first show that this proposal is perfectly consistent with the full set LE...

Sumario:In order to explain possible departures from the Standard Model predictions of $b\overline{b}$ and $c\overline{c}$ production at Z peak, we propose the existence of a Z' vector boson with enhanced couplings to quarks. We first show that this proposal is perfectly consistent with the full set LEP1/SLC results. We then show that there is a predicted range for enhanced Z' $q\overline{q}$ couplings which explains, for Z' masses in the TeV range, the excess of dijet events seen at CDF and leads to visible deviations at LEP2.
