Chromofields of Strings and Baryons

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 $B=(320MeV{)}^4$ 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.
