Lattice Methods For Quantum Chromodynamics

Numerical simulation of lattice-regulated QCD has become an important source of information about strong interactions. In the last few years there has been an explosion of techniques for performing ever more accurate studies on the properties of stro

Large $N_c$ Thermodynamics with Dynamical Fermions

Autor: Daniel C. Hackett, Thomas Alan DeGrand, Ethan T. Neil

Publikováno v: Proceedings of The 36th Annual International Symposium on Lattice Field Theory — PoS(LATTICE2018).

We present a progress report on our investigation of the thermodynamics of QCD with $N_f=2$ flavors of dynamical Wilson fermions in the limit of a large number of colors $N_c$. To date, studies of the thermodynamics of QCD at large $N_c$ have been li

Quark loop effects with an improved staggered fermion action

Autor: Kostas Orginos, Steven Gottlieb, Carleton E. DeTar, T. Burch, Doug Toussaint, Robert L. Sugar, Claude Bernard, Urs M. Heller, Thomas Alan DeGrand

Publikováno v: Nuclear Physics B - Proceedings Supplements. 94:237-241

We have been studying effects of dynamical quarks on various hadronic observables, using our recently formulated improvement for staggered fermions. To illustrate improvement, we show that the light hadron spectrum in the quenched approximation gives

tfB quenched and unquenched

Autor: Thomas Blum, Carleton E. DeTar, J. Labrenz, Amarjit Soni, Steven Gottlieb, Jim Hetrick, Claude Bernard, Thomas Alan DeGrand, M. Wingate, Urs M. Heller, Robert L. Sugar, A. De, D. Toussaint, N. Ishizuka, Kari Rummukainen

Publikováno v: Nuclear Physics B - Proceedings Supplements. 47:459-462

Results for $f_B$, $f_{B_s}$, $f_D$, $f_{D_s}$, and their ratios are presented. High statistics quenched runs at $\beta=5.7$, $5.85$, $6.0$, and $6.3$, plus a run still in progress at $\beta=6.52$ make possible a preliminary extrapolation to the cont

Baryon density correlations in the quark plasma

Autor: Thomas Alan DeGrand, Claude Bernard, Robert L. Sugar, S. Gottlieb, D. Toussaint, Carleton E. DeTar, A. Krasnitz

Publikováno v: Nuclear Physics B - Proceedings Supplements. 30:319-322

As part of an ongoing effort to characterize the high temperature phase of QCD, we measure the quark baryon density in the vicinity of a fixed test quark and compare it with similar measurements at low temperature and at the crossover temperature. Su
