  The CMS collaboration at the LHC has reported a remarkable and unexpected
phenomenon in very high-multiplicity high energy proton-proton collisions: a
positive correlation between two particles produced at similar azimuthal
angles, spanning a large range in rapidity. We suggest that this "ridge"-like
correlation may be a reflection of the rare events generated by the collision
of aligned flux tubes connecting the valence quarks in the wave functions of
the colliding protons. The "spray" of particles resulting from the approximate
line source produced in such inelastic collisions then gives rise to events
with a strong correlation between particles produced over a large range of both
positive and negative rapidity. We suggest an additional variable that is
sensitive to such a line source which is related to a commonly used measure,
ellipticity.
