  Title:  Evidence for BFKL and saturation dynamics in high multiplicity 
collisions at the LHC

Abstract:
A novel QCD phenomenon, discovered in high multiplicity proton-proton 
and proton-nucleus collisions at the LHC, is the azimuthal collimation 
of pairs of charged hadrons that are widely separated in rapidity. We 
argue that these long range in rapidity ``ridge" correlations provide 
distinctive images of  the structure of chromo-electromagnetic
fields at very early times in these collisions. In particular, the 
systematics of the phenomenon provides evidence both for 
Balitsky-Fadin-Kuraev-Lipatov (BFKL)
renormalization group dynamics as well as gluon saturation in high 
energy QCD. Alternative scenarios, which interpret the ridge phenomenon 
in terms of collective flow are also discussed.
