Download or read book Lectures on Quark Matter written by W. Plessas and published by Springer. This book was released on 2008-01-11 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: This set of lectures deals with the transition from nuclear matter to quark matter. The reader will learn not only about the theory of quark-gluon plasmas but also how they are obtained in the laboratory through heavy-ion collisions or where they can be found in astrophysical objects such as compact stars. The book fills a gap between well-known textbook material and the research literature and is thus perfectly suited for postgraduate students who wish to enter this field, for lecturers looking for advanced material for their courses and for scientists in search of a modern source of reference on these topics.

Book excerpt: My research in lattice gauge theory during the past year is described. Several projects were completed dealing with QCD simulations including dynamical fermions. Under the DOE Grand Challenge program, a large scale calculation of the QCD spectrum with two light flavors of dynamical staggered quarks was carried out. This calculation is one of the most significant efforts to data to take into account the effects of dynamical fermions. Smaller lattice spacing and lighter quark masses were used than in previous attempts. QCD thermodynamics was studied on the ST-100 array processor and on an ETA supercomputer at the John von Neumann Supercomputer Center. On the ST-100, a study with two flavors of dynamical staggered quarks with am{sub q} = 0.025 and 0.0125 was carried out on a 123 x 8 lattice. These results give a rough estimate of the crossover couplings where we see the restoration of chiral symmetry. A study of QCD with dynamical Wilson fermions was carried out with N{sub t} = 4 to try to bring the study of QCD with dynamical Wilson fermions to the level that has been attained with staggered fermions over the past two years. We have calculated screening lengths to elucidate the properties of the high temperature phase. In the pure gluon theory, claims that the finite temperature deconfinement transition is second order, rather than first order, were investigated using a finite size scaling analysis. Our results support a first order transition. Finally, work was done to port computer code to new environments involving parallelism in order to pursue more ambitious calculations on more powerful hardware than the ST-100 and ETA10 used for the calculations reported here.

Available in PDF, EPUB and Kindle. Book excerpt: We present results for meson masses and decay constants measured on 243 x 64 lattices using the domain wall fermion formulation with an extension of the fifth dimension of L{sub s} = 16 for N{sub f} 2 + 1 dynamical quark flavors. The lightest dynamical meson mass in our set-up is around 331MeV. while partially quenched mesons reach masses as low as 250MeV. The applicability of SU(3) x SU(3) and SU(2) x SU(2) (partially quenched) chiral perturbation theory will be compared and we quote values for the low-energy constants from both approaches. We will extract the average light quark and strange quark masses and use a non-perturbative renormalization technique (RI/MOM) to quote their physical values. The pion and kaon decay constants are determined at those values from our chiral fits and their ratio is used to obtain the CKM-matrix element.

Available in PDF, EPUB and Kindle. Book excerpt: Starting from the relativistic gauge-invariant quark-antiquark Green function the authors obtain the relevant interaction in the one-body limit, which can be interpreted as the kernel of a non-perturbative Dirac equation. They study this kernel in different kinematic regions, reproducing, in particular, for heavy quark the potential case and sum rules results. They discuss the relevance of the result for heavy-light mesons and the relation with the phenomenological Dirac equations used up to now in the literature.

Available in PDF, EPUB and Kindle. Book excerpt: We report on a calculation of the effects of isospin breaking in Lattice QCD+QED. This involves using Chiral Perturbation Theory with Electromagnetic corrections to find the renormalized, non-degenerate, light quark masses. The calculations are carried out on QCD ensembles generated by the RBC and UKQCD collaborations using Domain Wall Fermions and the Iwasaki and Iwasaki+DSDR Gauge Actions with unitary pion masses down to 170 MeV. Non-compact QED is treated in the quenched approximation. The simulations use a $32^3$ lattice size with $a^{-1}=2.28(3)$ GeV (Iwasaki) and 1.37(1) (Iwasaki+DSDR). This builds on previous work from the RBC/UKQCD collaboration with lattice spacing $a^{-1}=1.78(4)$ GeV.
