      The measurements of the ΔI = 1 part of the parity violating nuclear force when combined with information on neutral current couplings from neutrino scattering and pion production experiments allow an estimate of the isoscalar admixture in the neutral current if it has a vector axial-vector structure has been shown.

    • Are weak vector bosons composite?

      More Details Abstract Fulltext PDF

      Recentcern$$p\bar p$$ collider data on anomalousZ° events suggest, among other possibilities, a composite structure for the weak intermediate vector bosons. We present a short review of these developments and examine how far the scenario for weak interactions with such composite models of the weak vector bosons presents a viable alternative to the standard electroweak theory. In particular, we show how the scale of the dynamics underlying the composite structure is set by the magnitude of the weak mixing angle sin2θw and point out the possibility of accommodating the anomalous$$Z^ \circ - l\tilde l\gamma $$ decay events presently observed within this picture.
