How Much do Heavy Quarks Thermalize in a Heavy Ion Collision?
Guy D. Moore, Derek Teaney
We investigate the thermalization of charm quarks in high energy heavy ion collisions. To this end, we calculate the diffusion coefficient in the perturbative Quark Gluon Plasma an…
The difference between n-dimensional regularization and n-dimensional reduction in QCD
J. Smith, W. L. van Neerven
We discuss the difference between n-dimensional regularization and n-dimensional reduction for processes in QCD which have an additional mass scale. Examples are heavy flavour prod…
Conical Flow induced by Quenched QCD Jets
J. Casalderrey-Solana, E. V. Shuryak, D. Teaney
Quenching is a recently discovered phenomenon in which QCD jets created in heavy ion collisions deposit a large fraction or even all their energy and momentum into the produced mat…
Resummations, Power Corrections and Interjet Radiation
George Sterman
Resummation in QCD provides insight into the evolution of final state jets from short to long distances, and of accompanying interjet radiation. Applications to event shapes, inclu…
Instanton-induced Azimuthal Spin Asymmetry in Deep Inelastic Scattering
Dmitry Ostrovsky, Edward Shuryak
It is by now well understood that spin asymmetry in deep inelastic scattering (DIS) can appear if two things are both present: (i) a chirality flip of the struck quark; (ii) a nonz…
Factorization of Hard Processes in QCD
John C. Collins, Davison E. Soper, George Sterman
We summarize the standard factorization theorems for hard processes in QCD, and describe their proofs.
