We analyze the structure of the high multiplicity events observed by the CMS Collaboration at the LHC. We argue that the bulk of the observed correlations is due to the production of a pair of jets with p t>15GeV/c. We also suggest that high multiplicity events are due to a combination of three effects: high underlying multiplicity for collisions at small impact parameters, upward fluctuations of the gluon density in the colliding protons, and production of hadrons in the fragmentation of dijets. The data analysis is suggested, which may clarify the underlying dynamics of the high multiplicity events and probe fluctuations of the gluon field as a function of x.
