b-Quark Hadrons - a Theoretical Laboratory for Color Magnetic Interaction

Marek Karliner, Tel Aviv University

I discuss several recent highly accurate theoretical predictions for masses of baryons containing the b quark, especially the heaviest baryon
discovered to-date - Omega_b(ssb) recently observed at Fermilab. I also point out an approximate effective supersymmetry between heavy quark
baryons and mesons and provide predictions for the magnetic moments of Lambda_c and Lambda_b baryons containing heavy c and b quarks. Proper treatment of the color-magnetic hyperfine interaction in Quantum Chromodynamics (QCD) is crucial for obtaining these results.
