Indications of QGP formation in p+p collisions at the LHC?

On September 21st 2010 the CMS Collaboration gave a seminar at CERN detailing the observation of long-range near-side angular correlations in p+p collisions at the LHC. A preprint was submitted to arXiv the same day:

Observation of Long-Range Near-Side Angular Correlations in Proton-Proton Collisions at the LHC

The significance of these two particle correlations in azimuthal angle and pseudo-rapidity space is that they are thought to be the result of a collective, hydrodynamic, response of a medium to fluctuations of a multi-particle initial state. The medium in question of course most likely being a Quark-Gluon-Plasma. (more…)
