      We present an interpretation of the recently observed phenomenon of rise of associated multiplicity with momentum transfer as an overlap effect of two independent physical processes, the first one dominating the small momentum transfer region and the second one correspondingly the large angle region.

    • 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.
