QCD and Heavy Ions
This short paper is an attempt to describe a theorist’s view of the goals of relativistic heavy ion program which has just entered the collider era. These goals are centered around understanding the properties and the critical behavior of Quantum Chromo–Dynamics (QCD) in the non–linear regime of high color field strength and high parton density. Some of the current theoretical challenges are hi...
متن کاملLattice QCD and heavy quarks
Quarks are bound into hadrons by the interaction of quantum chromodynamics (QCD), some aspects of which cannot be treated by perturbation theory. As a result, non-perturbative methods have been developed, of which lattice gauge theory is at present the leading contender. The study of hadronic properties of heavyquark systems is valuable for at least two reasons. (1) By peeling away effects of t...
متن کاملHeavy hadrons and QCD instantons.
Heavy hadrons are analyzed in a random and dilute gas of instantons. We derive the instanton-induced interactions between heavy and light quarks at next to leading order in the heavy quark mass and in the planar approximation, and discuss their effects on the hadronic spectrum. The role of these interactions in the formation of exotic hadrons is also discussed. PACS numbers: 11.15.Pg, 12.38.Cy,...
متن کاملHeavy Quarks and Lattice Qcd
The study of flavorand CP -violation is a vital part of particle physics [1]. Often lattice QCD is needed to connect experimental measurements to the fundamental couplings of quarks, which, in the Standard Model, are elements of the CabibboKobayashi-Maskawa (CKM) matrix. Usually the test of CKM is drawn as a set of constraints on the apex of the so-called unitarity triangle (UT). The Particle D...
متن کاملHeavy Quarks and QCD Matter
I present recent results on the theory of QCD matter production in high energy heavy ion collisions and on the interactions of heavy quarks in such environment. The centrality and rapidity dependence of hadron production is evaluated in semi–classical approach. The energy loss of heavy quarks in matter is computed. The heavy–to–light meson ratio (e.g., D/π) at moderate transverse momenta is dem...
