Query: From Leading Hadron Suppression to Jet Quenching at RHIC and at the LHC   In nucleus-nucleus collisions at the Relativistic Heavy Ion Collider (RHIC),
one generically observes a strong medium-induced suppression of high-pT hadron
production. This suppression is accounted for in models which assume a
significant medium-induced radiative energy loss of high-pT parent partons
produced in the collision. How can we further test the microscopic dynamics
conjectured to underly this abundant high-pT phenomenon? What can we learn
about the dynamics of parton fragmentation, and what can we learn about the
properties of the medium which modifies it ? Given that inelastic parton
scattering is expected to be the dominant source of partonic equilibration
processes, can we use hard processes as an experimentally well-controlled
window into QCD non-equilibrium dynamics ? Here I review what has been achieved
so far, and which novel opportunities open up with higher luminosity at RHIC,
and with the wider kinematical range accessible soon at the LHC.
