    Notes: [Auszug] DURING the past decade or so, several measurements have been made of the flux of the cosmic-ray particles in the wide range of energy from 109 to 1020 eV. These were based at the lower energy end on the flux of nuclei observed at different geomagnetic latitudes and at energies greater than 1015 eV ...

    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.

    Notes: Abstract The string model of Artru and Mennessier predicts that the fragmentation functions for mesons containing heavy quarks are concentrated near fractional momentumz∼1, with width ∼1/μ where μ is the mass of the heavy quark.

    A note on the fragmentation functions of discrete particles on the Artru-Mennessier string (1984)

    Notes: Abstract The Artru-Mennessier model for the breakup of strings of colour connecting partons yields a continuous hadron spectrum. I show how the same physical picture may be implemented with a spectrum of discrete hadrons, the Artru-Mennessier model being recovered in the limit of a dense spectrum. As in the Artru-Mennessier model, fragmentation functions are mass dependent and heavy hadrons are dynamically suppressed relative to lighter.

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

    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.

    Extended sources, final state interactions and Bose-Einstein correlations (1988)

    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.

    Investigations into the origin of the spurious 17 keV neutrino signal observed in35S beta decay (1995)

    Notes: Abstract An exhaustive study has been made of the β spectrum of35S, recorded with a Si(Li) detector. The object was to identify the origin of a distortion in the35S β spectrum some 17 keV below the end point, reported over three years ago and interpreted then as evidence for a 17 keV neutrino. Measurements with different source-detector spacings and with varied collimation have shown that there is a long range curvature in the Kurie plot which is a sensitive function of configuration, but the principal origin of the distortion is energy loss in the35S sources. The35S sources, prepared by chemical adsorption of Ba35SO4 on a gold substrate, are clumped and locally thick. Electrons near the end point lose ∼0.3 keV in the source material and if this is taken into account the spectra are well fitted without any admixture of 17 keV neutrino. The source thickness has been investigated with a proton microprobe and determined from both source tilting and the yield of bariumK X-rays; these studies are discussed in detail. The uncertainties in and justification for the form of the electron response function employed are also thoroughly discussed. If there is no systematic error common to the majority of 14 independent sets of35S data, the admixture of 17 keV neutrino is 〈10−3 (95% CL). A simple search for a kink at 150 keV in the combined data from all 14 runs yielded a limit of 1.8×10−3 (95% CL). The end point of the35S β spectrum is found to be 167.60±0.05 keV.
