    Notes: Abstract The isospin 2 ππ interaction is repulsive, thes-wave phase shift reaching ∼−20° at the mass of the ρ meson. Theπ ± π ±correlation function shows a strong Bose-Einstein enhancement but no clear sign of this dynamical repulsion. I present the theory of final state interactions appropriate to particle production from an extended source and demonstrate that the data are entirely consistent with the known features of the ππI=2 interaction. The results are relevant to multiple pion production ine + e − annihilation, hadronic reactions and heavy ion collisions.

    On the origin of approximate KNO scaling ine + e − annihilation (1986)

    Notes: Abstract KNO scaling of the multiplicity distribution in hadronic final states was originally derived as a consequence of Feynman scaling. We show that in iterative models of hadron production in jets, incorporating Feynman scaling, KNO scaling obtains only in the limit when the width of the multiplicity distribution tends to zero. Within the context of the models currently employed to describee + e − annihilation into hadrons, the apparent KNO scaling observed is an accidental consequence of effects which violate Feynman scaling.

    Bose Einstein symmetrisation, coherence and chaos; with particular application toe + e − annihilation (1985)

    Notes: Abstract The phenomenon of Bose-Einstein correlation within the debris of hadronic final states is discussed in simple terms, with particular attention to the nature of coherent and chaotic sources. The Artru-Mennessier string is taken as a model for the pion source ine + e − annihilation and the predicted Bose-Einstein correlations between like pion pairs evaluated. The results are in good accord with such data as exist.
