Jet Quenching
High-pt particles produced in nucleus-nucleus collisions constitute a powerful tool to study the medium properties. The energy loss resulting from the propagation of these particles in the produced medium translates into a suppression of the high-pt yields. These effects are usually associated to medium-induced gluon radiation which, in turn, predicts a broadening of the jet-like signals. Both ...
متن کاملJet quenching via jet collimation
The strong modifications of dijet properties in heavy ion collisions measured by ATLAS and CMS provide important constraints on the dynamical mechanisms underlying jet quenching. In this work, we show that the transport of soft gluons away from the jet cone — jet collimation — can account for the observed dijet asymmetry with values of q̂ L that lie in the expected order of magnitude. Further, w...
متن کاملHeavy quark jet quenching with collisional plus radiative energy loss and path length fluctuations
With the QGP opacity computed perturbatively and with the global entropy constraints imposed by the observed dNch/dy ≈ 1000, radiative energy loss alone cannot account for the observed suppression of single non-photonic electrons. We show that collisional energy loss, which previously has been neglected, is comparable to radiative loss for both light and heavy jets and may in fact be the domina...
متن کاملJet Quenching at Rhic
We present high transverse momentum (p T) measurements made at the Relativis-tic Heavy Ion Collider (RHIC) for Au+Au, d+Au, and p+p collisions at √ s N N = 200 GeV, as well as for Au+Au collisions at √ s N N = 62 GeV. We observe a suppression in the yield of high p T hadrons measured in central Au+Au collisions, relative to the yield in p+p collisions scaled by the number of binary nucleon-nucl...
