World of basic attributes: valency and color

Within the gauge theory approach to color, the compatibility of the hypotheses of integer-charge quarks and physical color with lepto-production experiments is discussed. Two important consequences of this hypothesis for deep inelastic phenomena are: color-gluons contribute in a scale-invariant manner to structure functions; (sigma/sub L/sigma/sub T/) is nonvanishing and a function of x only. It is suggested that the anomalous (μe)-events observed at SPEAR are progenies of integer-charge quark-pairs produced by e-e+-annihilation decaying into leptons (a possibility which was suggested by the quark-lepton unification hypothesis). It is remarked that the dimuons produced by neutrinos with their observed rate can be attributed to production of charged color-gluons, while the prompt leptons observed in hadronic collisions may be attributed to the production of quarks and/or color gluons in pairs. Distinguishing features of these explanations and also distinctive signatures for color are noted
