【 摘 要 】

In the fragmentation of a color flux tube in high-energy pp collisions or e+-e-annihilations, the production of pairs along a color flux tube precedes the fragmentation of the tube. The local conservation laws in the production of these 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 Δφ ∼ 0 but enhanced at Δφ ∼ π, within a rapidity window Δy∼1/(dN/dy).
