有限化学势下六个时间切片的QCD
QCD at finite chemical potential with six time slices
摘要:
我们研究的重子数磁化率的泰勒展开,因此,压力,在一系列的重子化学势(mu_B)通过晶格模拟与轻动力学交错夸克在一个更精细的晶格截止a=1/6 T。我们确定了μ B=0时的QCD交叉耦合。我们求出了该级数在不同温度下的收敛半径,并将QCD临界点的位置限定在T^E/T_c = 0.94和μ_B^E/T < 1.8。我们还研究了外推的各种affiliatibilities和联系有限的化学势。
英文摘要:
We investigate the Taylor expansion of the baryon number susceptibility, and hence, pressure, in a series in the baryon chemical potential (mu_B) through a lattice simulation with light dynamical staggered quarks at a finer lattice cutoff a=1/6T. We determine the QCD cross over coupling at mu_B=0. We find the radius of convergence of the series at various temeperatures, and bound the location of the QCD critical point to be T^E/T_c = 0.94 and mu_B^E/T < 1.8. We also investigate the extrapolation of various susceptibilities and linkages to finite chemical potential.
