  Gauge invariance of QCD dictates the presence of string junctions in the wave
functions of baryons. In high-energy inclusive processes, these baryon
junctions have been predicted to induce the separation of the flows of baryon
number and flavor. In this paper we describe this phenomenon using the
analog-gas model of multiparticle production proposed long time ago by Feynman
and Wilson and adapted here to accommodate the topological expansion in QCD. In
this framework, duality arguments suggest the existence of two degenerate
junction-antijunction glueball Regge trajectories of opposite $\cal{C}$-parity
with intercept close to 1/2. The corresponding results for the energy and
rapidity dependence of baryon stopping are in reasonably good agreement with
recent experimental findings from STAR and ALICE experiments. We show that
accounting for correlations between the fragmenting strings further improves
agreement with the data, and outline additional experimental tests of our
picture at the existing (RHIC, LHC, JLab) and future (EIC) facilities.
