Description
The sPHENIX proposal is for a second generation experiment at RHIC,
which will take advantage of the increased luminosity due to
accelerator upgrades, and allow measurements of jets and jet
correlations with a kinematic reach that will overlap with
measurements made at the Large Hadron Collider (LHC). Particle jets,
formed when a hard scatter parton fragments and then hadronizes into a
spray of particles, were proposed as a probe of the Quark Gluon Plasma
formed in heavy-ion collisions. As they traverse the QGP, the hard
scattered partons probe the medium at a variety of length scales,
which is called jet quenching. To answer the fundamental questions of
how and why partons lose energy in the QGP, we need to characterize
both the medium induced modification of the jet fragmentation pattern
and the correlation of the lost energy with the jet axis. Some
observables that help elucidate these effects are gamma-jet
correlations and jet fragmentation functions, which require the
precise tracking and calorimetry that sPHENIX will have. We will show
the performance of these observables as well as that for jet and
hadron spectra measurements, which are necessary for a baseline
understanding, based on detector simulations.
