Query: Signatures of Flux Tube Fragmentation and Strangeness Correlations in pp
  Collisions   In the fragmentation of a color flux tube in high-energy $pp$ collisions or
$e^+$-$e^-$ annihilations, the production of $q$-$\bar q$ pairs along a color
flux tube precedes the fragmentation of the tube. The local conservation laws
in the production of these $q$-$\bar q$ pairs will lead to the correlations of
adjacently produced hadrons. As a consequence, the fragmentation of a flux tube
will yield a many-hadron correlation in the form of a chain of hadrons ordered
in rapidity, with adjacent hadrons correlated in charges, flavor contents, and
azimuthal angles. It will also lead to a two-hadron angular correlation between
two hadrons with opposite charges or strangeness that is suppressed at $\Delta
\phi\sim 0$ but enhanced at $\Delta \phi\sim \pi$, within a rapidity window
$\Delta y $$\sim$$1/(dN/dy)$.
