Description

  • Content Description: Gauge invariant extended configurations are considered for 3 fundamental (quarks) or adjoint (gluons) particles. For 3 quarks it is proved that the only possible gauge-invariant configuration is the Y-shaped one, proposed long ago, while the triangular one proposed recently is ruled out. For adjoint sources both configurations are possible. Static potential is computed in all cases. For baryons the Y-shaped configuration leads to a significant depletion of field-strength density at the string-junction position, which decreases the effective potential slope at R {approx} 0.5 fm by 10-15%, as observed on the lattice. For adjoint sources the Y-shaped and {Delta}-shaped potentials are very close, leading to almost degenerate masses of 3--3g glueballs and odderon trajectories.
