Abstract.

We calculate color electric fields of quark/antiquark (\(\bar{q}q\)) and 3-quark (qqq) systems within the Chromodielectric Model (CDM). We explicitly evaluate the string tension of flux tubes in the \(\bar{q}q\)-system and analyze their profile. To reproduce results of lattice calculations we use a bag pressure \(B = (320\; {\mathrm {MeV}})^4\) from which an effective strong-coupling constant \(\alpha_{s} \approx 0.3\) follows. With these parameters we get a Y-shaped configuration for large qqq-systems.
