  Local gauge invariance of the baryon wave function leads to the emergence of
a baryon junction, where three (or $N$, in $SU(N)$ gauge theory) string
operators merge. The existence of baryon junction dramatically affects the
dynamics of baryon stopping at high energies, and the corresponding predictions
are supported by the recent data from STAR Collaboration at the Relativistic
Heavy Ion Collider. Here we outline the ways in which the baryon junctions can
be tested in semi-inclusive deep inelasttic scattering at Jefferson Laboratory
and the future Electron Ion Collider.
