Description
Since baryon is a composite particle, one may wonder which degrees of freedom are carrying the conserved charges, including the baryon number. A baryon junction, that arises naturally in a gauge-invariant description of the baryon wavefunction, is a perfect candidate to associate the baryon number with. In this talk I will discuss various possibilities to test the flow of baryon number experimentally, including the recent proposal of studying semi-inclusive deep inelastic scattering. The rapidity distribution of baryons produced in high-energy processes depends crucially on the Regge intercepts of exotic states with hidden baryon number. I will go over recent developments in the Feynman-Wilson analog gas model that can be used to estimate such intercepts. Finally, I will explore the possibility of identifying such exotic states as glueballs with lattice QCD.
