    ABSTRACT: Within a hadron bag valence quarks have a distribution of momenta, which, at low energies allows the kinematic scaling violations in deep inelastic scattering to be calculated. Using a simple model for this distribution we can succesfully account for the data between 2 and 6 (GeV/c)2. At higher momenta, “non-kinematic” effects are required.

    ABSTRACT: It is shown that the experimental limit on the proton lifetime requires a very small quark radium in three-fermion (rishon) composite models.

    ABSTRACT: An economical scheme for composite quarks and leptons is suggested. The basic vector particles of the theory are, like gluons, confined and the intermediate vector bosons are also composites. A possible “reason” for the existence of families emerges.

    ABSTRACT: We show how the graded Lie-algebra structure of a recent derivation of the Salam-Weinberg model might arise from the form of allowed transformations on the lepton lagrangian in a 6-dimensional space. The possibilities that the model might allow two identically coupled leptonic sectors, and others in which the chiralities are reversed, are discussed.

    ABSTRACT: We show that elementary kinematics yield a kT distribution which varies with x. The nature of the relationship depends on the form of the quark wavefunction. We calculate explicitly in the MIT bag model.

    ABSTRACT: We discuss the role of interquark forces in a bag model description of the nuclear force. We conclude that the classical bag binding energy is not a good indication of the true binding energy.

    [Show abstract] [Hide abstract]
    ABSTRACT: We discuss the quantisation of one-dimensional MIT bags by expanding the fields as a sum of classical modes and truncating the series after the first term. We obtain the lowest states of a bag in a world containing two scalar quark fields. Problems associated with the zero-point oscillations of the field are discussed.

    ABSTRACT: Two simple models of diffractive scattering are investigated. Recently made suggestions that the nature of the eigenvalue spectrum arises from a complicated proton structure and that the peripherality of inelastic diffraction is a general consequence of absorption are not supported.

    ABSTRACT: We propose a simple prescription for quantising a six-quark bag. Calculations in one dimension appear to give the right order of magnitude for the effective nucleon-nucleon potential.
