[en] This paper deals with the hadronization process of quark system. A phenomenological potential is introduced to describe the interaction between a quark pair. The potential depends on the color charge of those quarks and their relative distances. Those quarks move according to classical equations of motion. Due to the color interaction, coloring quarks are separated to form color neutral clusters which are supposed to be the hadrons. (author)

[en] Some 50 years ago, just for fun, I began playing around with different types of particle statistics. Those investigations led to a surprising application

[en] The existing experimental information on baryonium is compared in detail with the predictions of the diquark-antidiquark colour molecular (diquonium) model. The correspondence is found encouraging and close to a confirmation of colour as a genuine degree of freedom in hadron specroscopy

[en] Some simple aspects of spectroscopic consequences and expected exchange mechanisms in the colour isomer multiquark model are showed

[en] The author discusses the role played by gluons in various phenomena of hadronic and deep inelastic physics, and how in hadronic physics one might hope to isolate a gluon jet. (author)

[en] We show how experiments concerning the isobar content of the deuteron that apparently are contradicting each other can be reconciled by the quark model with hidden colour. (orig.) 891 HSI/orig. 892 HIS

[en] This is a review of applications of the Color Glass Condensate (CGC) to the phenomenology of relativistic heavy-ion collisions. The initial stages of the collision can be understood in terms of the nonperturbatively strong nonlinear glasma color fields. We discuss how the CGC framework can and has been used to compute properties of the initial conditions of AA collisions. In particular this has led to recent progress in understanding multiparticle correlations, which can provide a directly observable signal of the properties of the initial stage of the collision process.

[en] An introduction to calculations with color symmetry is provided for non-experts, by giving examples. The observabillity of color symmetry, even though only colorless states might exist, is emphasized

[en] We attribute the phenomenon known as 'the ridge' to long range initial state correlations from Color Glass Condensate flux tubes and later stage radial flow. We show that this description can explain the amplitude and azimuthal width of the soft ridge and nearly explain that of the hard ridge, suggesting that the two are essentially the same phenomenon.
