[en] The shape and the energy-variation of multiplicity distributions after the jet-component is removed agree with the predictions of the branching model whose dynamical contents and other consequences are discussed. Other phenomenological aspects of multiplicity distributions are also discussed, including the dependence on the rapidity window and the necessity for two components

[en] It is shown that none of the popular models suggested to explain the EMC effect seem satisfactory. A new point of view on the effect as a simple relativistic phenomenon is presented and is shown to be favoured by NA4 data

[en] The implications of scalar confinement for gap equation, Coulomb gauge models for chiral symmetry breaking in QCD are discussed

[en] It is pointed out that in models of quark confinement the usual analysis of spin dependent forces in terms of scalar or vector potentials may be inappropriate. The special role that the self energy plays in such models and its consequences for heavy quarkonia are discussed

[en] We discuss the consistency of the instanton calculus for supersymmetric QCD

[en] By means of a SUSY generalization of Bogoliubov - MIT confinement we restrict supermultiplets of particles to small regions of space. SUSY PCAC is used to introduce pseudo Goldstone particles living outside the bag. Supersymmetry is automatically broken so that the pseudo Goldstone fermions are much lighter than the bosons

[en] The possibility of a bound-state effect in the quark-quark interaction is discussed. If such dynamical diquarks exist, they should play a role in the formation and decay of a QCD plasma, as probed in relativistic heavy-ion collisions. In an intermediate temperature range, just above the critical temperature, a diquark plasma component is expected to be important. Quantitative results within a particular model, the Stockholm diquark model, are presented. Possible experimental signatures of such a diquark plasma are suggested

[en] String theories have recently been regarded as candidates for the fundamental theory of nature. In this short review, an elementary exposition is presented on the key ingredients involved for having an ultraviolet finite quantum theory
