	QCD matter - Wikipedia, the free encyclopedia
		The equations of QCD predict that a sea of quarks and gluons should be formed at high temperature and density.
		Ordinary atomic matter as we know it is really a mixed phase, droplets of nuclear matter (nuclei) surrounded by vacuum, which exists at the low-temperature phase boundary between vacuum and nuclear matter, at μ=310MeV and T close to zero.
		The phase structure of quark matter remains mostly conjectural because it is difficult to perform calculations predicting the properties of quark matter.

	Lattice QCD - Wikipedia, the free encyclopedia
		Lattice Quantum Chromodynamics (Lattice QCD) is the theory of quarks and gluons formulated on a space-time lattice.
		Analytic or perturbative solutions in QCD are hard or impossible due to the highly nonlinear nature of the strong force.
		Most importantly, Lattice QCD provides the framework for investigation of non-perturbative phenomena such as confinement and quark-gluon plasma formation, which are intractable by means of analytic field theories.

		Exploration of the phase diagram of strongly interacting matter as a function of temperature and baryon number density, using a class of models for two-flavor QCD in which the interaction between quarks is modelled by that induced by instantons.

	QCD and Dense Matter: From Lattices to Stars (INT-04-1)
		High-density QCD is a new frontier in the investigation of the QCD phase diagram.
		The theoretical study of the "condensed matter physics" of QCD has led to several surprising discoveries, such as robust color superconducting phases and a new color-flavor-locked phase of quark matter.
		We would like to understand how to combine perturbative QCD and effective field theory techniques in order to perform systematic studies of the phase diagram and the structure of matter at high baryon density.

		Lattice QCD calculations solve the QCD equations on a discretized lattice but are only reliable at zero or low chemical potentials.
		To do so, it is very important to implement a model with a broad applicability including nuclear matter, finite nuclei and chiral symmetry restoration to be able to simultaneously study different observables within a unified approach using the same set of parameters for all calculations and to fix remaining free parameters.
		But, as we will be able to show, the investigation of the properties of neutron stars and the phase structure of hadronic matter strongly constrain these couplings and thus lead to much stronger predictions for the EoS at high energies and temperature.

		These data established that the previously observed strong jet quenching effect and the mono-jet topology observed in central Au+Au reactions must be due to final state interactions in the dense QCD matter produced in those reactions.
		Jet quenching in high energy nuclear collisions was proposed in collaboration with Michael Pluemer and Xin-Nian Wang as a novel probe of ultra-dense QCD matter produced at RHIC and higher energies.
		While many details of the QGP dynamics are not yet understood, the existence of this ultra-dense form of QCD matter is now established via its high opacity to penetrating jets, its remarkable bulk elliptic flow patterns, and critical null control experiments.

		Twenty or even fifteen years ago, this activity was commonly called "testing QCD." Such is the success of the theory, that we now speak instead of "calculating QCD backgrounds" for the investigation of more speculative phenomena.
		So if QCD is to describe the real world, the chiral symmetry must be spontaneously broken, much as rotational symmetry is spontaneously broken in a ferromagnet.
		I have tried to convince you of two things: first, that the fundamentals of QCD are simple and elegant, and second, that these fundamentals come into their own, and directly describe the physical behavior of matter, under various extreme conditions.

		On the basis of a QCD-inspired partonic description, a number of critical issues in heavy-ion collisions at RHIC energies and beyond have been addressed: the initial condition of the dense matter formed, the approach of such dense parton matter to equilibrium, and the probes of the early parton dynamics.
		Chiral models of the nuclear force will be extended to describe hypernuclei and the equation of state for both strange and charmed matter, with relevance for both heavy-ion physics and compact stars.
		Associated precursor signals for the chiral phase transition in dense matter will be sought and the possible transition to a kaon condensed phase in the core of a neutron star will be also studied.

	THE QCD VACUUM, HADRONS AND SUPERDENSE MATTER
		Three major issues — the structure of the QCD vacuum, the structure of hadrons, and the physics of hot/dense matter — are addressed as physics problems.
		Therefore, when discussing any specific subject, the book attempts to incorporate (1) all the solid theoretical results, (2) experimental information, and (3) results of numerical (lattice) simulations, which are playing an increasing role in quantum field theory in general, and the development of QCD in particular.
		The QCD Vacuum, Hadrons and Superdense Matter takes the reader from the first encounter with the subject to the front line of research, as quickly as possible.

	Welcome to Ivan Vitev's Home Page
		Quantum Chromodynamics (QCD) and asymptotic freedom predict the existence of a new state of matter, the quark-gluon plasma (QGP), at exceedingly high temperatures and energy densities similar to the ones that characterized the first few microseconds after the Big Bang.
		The quest for such a deconfined state of QCD has led to the highly successful program at the Relativistic Heavy Ion Collider (RHIC) and will be an integral part of the program at the Large Hadron Collider (LHC).
		Comparison between data and theory is suggestive of the creation of a deconfined state of QCD with energy density on the order of 100 times normal nuclear matter density.

		It is believed that shortly after the creation of the universe in the Big Bang all matter susceptible to QCD was in a state called the Quark Gluon Plasma (QGP).
		However, there exists mounting evidence that RHIC has indeed created a hot and dense state of deconfined QCD matter with properties similar to that of an ideal fluid (see here for a BBC news article featuring quotes of Prof.
		Only through the application of dynamical models of heavy-ion collisions and the comparison of their predictions with data, may a link be formed between the observable hadronic and leptonic final state of the heavy-ion reaction and the transient deconfined state of quarks and gluons.

	STRONG AND ELECTROWEAK MATTER 2004
		This volume presents an authoritative review of the physics of strongly and electroweakly interacting elementary particle matter in extreme conditions that prevailed in the very early Universe, and which are being recreated in high energy physics laboratories today.
		Based on the discussions of more than a hundred experts at the Strong and Electroweak Matter 2004 Meeting, this volume contains an up-to-date overview of present ideas on QCD matter: quark-gluon plasma in heavy ion collisions, phase structure, kinetics, thermalization and transport properties.
		Also discussed are topics related to the cosmology of the early Universe, dark matter, inflation and creation of particle-antiparticle asymmetries.

		An ongoing project (Kajantie, Laine, Rummukainen, Schröder, [ hep-ph/0007109], [ hep-lat/0110122]) is to extend analytic computation of the free energy of hot QCD as far as theoretically possible, to a limit beyond which one must proceed by numerical means.

	Physics & Theoretical Colloquia Abstract
		Studies of QCD Matter at the Large Hadron Collider
		The research of the past few years at RHIC has produced a number of striking results which are leading to a deeper understanding of the properties of QCD matter.
		It is expected that heavy ion collisions at the Large Hadron Collider (LHC) will provide a new, and complimentary, view of the underlying physics and test the pictures emerging from the RHIC results.
