摘要：

We show that the key features of the CMS result on the ridge correlation seen for high multiplicity events in root s = 7 TeV proton-proton collisions at the LHC can be understood in the Color Glass Condensate framework of high energy QCD. The same formalism underlies the explanation of the ridge events seen in A + A collisions at RHIC, albeit it is likely that flow effects may enhance the magnitude of the signal in the latter.
