Plots were formatted to fit my talk My talk is biased Sorry for missing references I am not talking about pA I would not be able to cover all Sorry for dropping your best plot Stay tuned! Miss- interpretation is all my fault Sasha Milov new in HI QCD @ cosmic E - V, Paris June 12, 2012

Binary scaling at RHIC. ~kind of, but leaving room for doubts +CuCu (preliminary) New: data reanalyzed, baseline from new p+p sample, now more convincing Sasha Milov new in HI QCD @ cosmic E - V, Paris June 12, 2012
Binary scaling at LHC. CMS arXiv:0397962 [nucl-ex] PLB697 (2011) 294-312 ATLAS-CONF-2011-078 ATLAS PLB697 (2011) 294-312 All hints in one direction, but uncertainties are large Sasha Milov new in HI QCD @ cosmic E - V, Paris June 12, 2012

Jet Fragmentation Pb Pb Pb Pb = log (1/z) • Leading and sub-leading jets in PbPb fragment like jets of corresponding energy in pp collisions • So, where the energy is? arXiv:1205.5872 Sasha Milov new in HI QCD @ cosmic E - V, Paris June 12, 2012
Where is the jet energy? in cone out of cone (0-30)% Inside the cone high pT tracks are unbalanced (AJ > 0). Outside the cone low track are unbalanced with an opposite sign. Summing up the two restores the balance. Sasha Milov new in HI QCD @ cosmic E - V, Paris June 12, 2012
