Searching for the Next Yukawa Phase of QCD
Abstract
Description
QCD predicts that the interactions between quarks and gluons change from a confining to a screened Yukawa form above a critical temperature $T_c\sim 150$ MeV. In this talk, I review some of the key observables in heavy ion reactions which are being used to search for this new partonic Yukawa phase at SPS and RHIC. These include collective observables such as $dE_\perp/dyd^2p_\perp$, meson interferometry, jet quenching, and $J/ψ$ suppression.
