Jet Tomography in Heavy Ion Collisions

Experiments at the Relativistic Heavy Ion Collider RHIC in Brookhaven show for the first time a significant quenching of high-p⊥ leading hadron spectra. In particular, transverse momentum spectra for neutral pion 1,2 and charged hadron 1,3 are suppressed if compared to spectra in p+p collisions rescaled by the number of binary collisions. This suppression is most pronounced (up to a factor ∼ 5)...

Elucidating Jet Energy Loss in Heavy Ion Collisions

Over the last eight years, the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory (BNL) has been providing heavy ion collisions in the attempt to create the Quark-Gluon Plasma (QGP) within the laboratory. Some of the most striking data from the first few years at RHIC were results from the apparent interaction of hard scattered partons in the medium produced at RHIC. Singl...

Jet reshaping in heavy-ion collisions

We propose a new implementation of medium effects in jet structures in which a modification of the splitting function is included at every step in the typical final state parton shower. Although the main application of this new formalism will be at the LHC, it is interesting that, in the presence of a trigger bias to small number of splittings, non-trivial angular dependences could appear with ...

Jet Quenching in Heavy Ion Collisions

Jet Photoproduction in Peripheral Heavy-Ion Collisions

In peripheral relativistic heavy ion collisions at the Large Hadron Collider, jet+jet and photon+jet final states can be produced when a photon from the virtual photon field surrounding the nucleus interacts with a parton in the opposite nucleus (direct production). The virtual photon may also fluctuate into states with multiple gluons and qq pairs (resolved production), opening more channels f...
