Study of the ℤ3 symmetry in QCD at finite temperature and chemical potential using a worm algorithm
(2013-04-24)
Traditional Monte Carlo simulations of QCD in the presence of a baryon chemical potential are plagued by the complex phase problem and new numerical approaches are necessary for studying the phase diagram of the theory. ...
Freezing of the QCD coupling constant and the pion form factor
(World Scientific Publ Co Pte Ltd, 2003-01-01)
The possibility that the QCD coupling constant (alpha(s)) has an infrared finite behavior (freezing) has been extensively studied in recent years. We compare phenomenological values of the frozen QCD running coupling between ...
Spinodal decomposition in pure-gauge QCD
(2005-04-14)
Spinodal decomposition in a model of pure-gauge SU(2) theory that incorporates a deconfinement phase transition is investigated by means of real-time lattice simulations of the fully nonlinear Ginzburg-Landau equation. ...
The temperature dependence of the QCD running coupling
(2006-06-01)
We study the running of the QCD coupling with the momentum squared (Q 2) and the temperature scales in the high temperature limit (T > Tc), using a mass dependent renormalization scheme to build the Renormalization Group ...
QCD phenomenology with infrared finite SDE solutions
(2009-12-01)
Recent progress in the solution of Schwinger-Dyson equations (SDE), as well as lattice simulation of pure glue QCD, indicate that the gluon propagator and coupling constant are infrared (IR) finite. We discuss how this ...
Qcd Sum Rules for the G(KK*pi)(Q(2)) form factor
(World Scientific Publ Co Pte Ltd, 2003-01-01)
The QCD Sum Rules have been used to evaluate the form factor in the vertex KK*pi. The method of QCD Sum Rules is based on the duality principle in which it is assumed that the hadrons can simultaneously be described in two ...
Effects of latticeQCD EoS and continuous emission on some observables
(2006-04-11)
Effects of lattice-QCD-inspired equations of state and continuous emission on some observables are discussed, by solving a 3D hydrodynamics. The particle multiplicity as well ν 2 are found to increase in the mid-rapidity. ...
Effects of latticeQCD EoS and continuous emission on some observables
(Amer Inst Physics, 2006-01-01)
Effects of lattice-QCD-inspired equations of state and continuous emission on some observables are discussed, by solving a 3D hydrodynamics. The particle multiplicity as well nu(2) are found to increase in the mid-rapidity. ...
QCD vacuum topology and glueballs
(American Institute of Physics (AIP), 2004-01-01)
We outline a comprehensive study of spin-0 glueball properties which, in particular, keeps track of the topological gluon structure. Specifically, we implement (semi-hard) topological instanton physics as well as topological ...
Strong coupling QCD and effective hadronic interactions
(World Scientific Publ Co Pte Ltd, 2003-01-01)
The aim of this work is to implement the mechanism of link rearrangement predicted in the strong coupling limit of Hamiltonian lattice QCD - in a constituent quark model in which constituent quarks, links and junctions are ...
