8-th Summer School on Nuclear Physics, 3-12/07/12 94 Heavy Flavour: outlook • high statistics D measurements are D really as suppressed as light hadrons? • charm thermalisation? measure D mesons v2 • subtract D background pure B electron spectrum • beauty energy loss in wide p T range • in-medium fragmentation of b-tagged jets !
Conclusions • Pre-SPS and SPS studies: strangeness enhancement, charmonium suppression => indications of QGP • RHIC studies: jet quenching, flow => QGP becomes hot dense matter (ideal liquid) • in November 2010, the field of ultrarelativistic nuclear collisions has entered a new era with the start of heavy ion collisions at the LHC • abundance of hard probes • exciting results already from 2010 data sample • flow + fluctuations => death of ridge and Mach cone? • anomalies in proton yields & momentum distributions • pattern of jet and heavy flavour suppression => challenge to Eloss models • and the future looks bright! • ~ 150/µb delivered by LHC in 2011 • p-Pb run scheduled for 2012 precision measurements + handle on cold nuclear matter effects close in on dynamic and coupling properties of medium and … look out for surprises!!! 8-th Summer School on Nuclear Physics, 3-12/07/12 95
