Jet thermalization in QCD kinetic theory

QCD Plasma Instabilities and Bottom-Up Thermalization

Qcd and Jet Physics

The current status of the QCD coupling constant S and experimental and theoretical studies of hadronic jets are reviewed.

Multiparticle production and thermalization in high-energy QCD

We argue that multiparticle production in high energy hadron and nuclear collisions can be considered as proceeding through the production of gluons in the background classical field. In this approach we derive the gluon spectrum immediately after the collision and find that at high energies it is parametrically enhanced by ln(1/x) with respect to the quasiclassical result (x is the Bjorken var...

QCD resummation for jet substructures.

We provide a novel development in jet physics by predicting the energy profiles of light-quark and gluon jets in the framework of perturbative QCD. Resumming large logarithmic contributions to all orders in the coupling constant, our predictions are shown to agree well with Tevatron CDF and Large Hadron Collider CMS data. We also extend our resummation formalism to the invariant mass distributi...

Automated resummation of jet observables in QCD

Understanding the physics of event shapes and jet rates (collectively jet observables) requires a deep knowledge of QCD dynamics. Their distributions (defined as the fraction of events Σ(v) with the observable’s value V less than v) explore a wide range of physical scales, from the more inclusive region v = O(1), well described by fixed order perturbative (PT) calculations, to the extreme exclu...
