Abstract

I review recent developments in the CGC approach to high-energy collisions. The focus is on topics related to the Quark Matter conference, specifically on predictions for the p+Pb run at the LHC; as an added bonus some of these predictions are confronted with first data taken during the p+Pb machine performance test at the LHC performed in september 2012. I also highlight recent work related to particle production fluctuations, suppression of nuclear modification factors in p+A from rcBK evolution, (partial) NLO corrections in forward production, and photon-hadron as well as di-hadron correlations.
