Radiative W and Z Decays and Spontaneous R-Parity Violation

We point out that in a class of supersymmetric models where R-parity violation is induced by the spontaneous breaking of local B − L symmetry, the R-parity violating W decay W → l̃γ and Z decay Z → ν̃γ, forbidden in the minimal supersymmetric standard model (MSSM), occur at an enhanced rate compared to other models with R-parity breaking. We find that the branching fractions for these modes can b...

Baryonic Z ′ connection of LEP R b , c data with Tevatron ( W , Z , γ ) bb̄ events

The mixing of a new Z ′ boson with the Z significantly improves the fit to the LEP precision electroweak data, provided that the Z ′ couples mainly to quarks. If M Z 2 < 200 GeV, the s-channel Z 2 production and (W, Z, γ)Z 2 pair production cross sections at the Tevatron give an excess above QCD of b ¯ b and (W, Z, γ)b ¯ b events, respectively, with invariant mass m(b ¯ b) ≈ M Z 2 , which provi...

W and Z Physics

The electroweak theory elegantly combines the electromagnetic and weak forces, explaining a wide range of interactions using a gauge theory with just three parameters. The theory predicted the W and Z weak gauge bosons before they were directly observed in 1983, and its detailed predictions of W and Z boson properties have been tested to such precision that they now serve as probes for new part...
