1. Multi-hadron cluster triggered correlations
(proto-jets?)‏
Away-side spectrum
Motivation: explore jet-biases in di-hadron correlations Start developing jet reconstruction
0-12% Au+Au
Multi-hadron trigger
Add GeV trigger R
Seed
Secondary Seeds
Associated track
Ratio cluster/di-hadron analysis
Use cluster energy for trigger:
- R = 0.3
- pT,seed > 5 GeV
- pT,sec seed > 3 GeV
Single-hadron and multi-hadron triggers give similar result
Enough statistics for large dynamic range (pTrig up to 15 GeV)‏
In progress: differential studies+comparison to Pythia
