The Physics Case for sPHENIX What are the inner workings of the QGP?

ments is given in Section 1.5. We note that enhancements in q̂ above the critical temperaturemay be a generic feature of many models, as illustrated by the three conjectured evolutions,and so underscore the need for detailed measurements of quark-gluon plasma propertiesnear the transition temperature.

All measurements in heavy ion collisions are the result of emitted particles integrated overthe entire time evolution of the reaction, covering a range of temperatures. Similar to thehydrodynamic model constraints, the theory modeling requires a consistent temperatureand scale dependent model of the quark-gluon plasma and is only well constrained byprecision data through different temperature evolutions, as measured at RHIC and theLHC.

Scattering from Thermal Mass Gluons?

Figure 1.7: (Left) Diagram of a quark exchanging a virtual gluon with an unknown object inthe QGP. This highlights the uncertainty for what sets the scale of the interaction and whatobjects or quasiparticles are recoiling. (Right) Diagram as a function of the Q2 for the netinteraction of the parton with the medium and the range of possibilities for the recoil objects.

1.3 What are the inner workings of the QGP?

A second axis along which one can investigate the underlying structure of thequark-gluon plasma concerns the question of what length scale of the medium is beingprobed by jet quenching processes. In electron scattering, the scale is set by the virtualityof the exchanged photon, Q2. By varying this virtuality one can obtain information overan enormous range of scales: from pictures of viruses at length scales of 10�5 meters, to
