有限温度下双味QCD手性跃迁的普适性和标度性

Universality and Scaling at the chiral transition in two-flavor QCD at finite temperature

Tereza Mendes

摘要:

有限温度双简并轻夸克QCD中相变的阶数是一个悬而未决的问题,对应于QCD零密度相图中的最后一个问号。我们认为,建立在这种情况下的过渡的性质也是一个至关重要的测试格点量子色动力学的数值模拟,允许精确估计可能的系统误差相关的,例如,选择费米子模拟算法或费米子的离散化配方。

英文摘要:

The order of the phase transition in finite-temperature QCD with two degenerate light quarks is still an open problem and corresponds to the last question mark in the zero-density phase diagram of QCD. We argue that establishing the nature of the transition in this case is also a crucial test for numerical simulations of lattice QCD, allowing precise estimates of possible systematic errors related e.g. to the choice of fermion-simulation algorithm or of discretized formulation for fermions.
