${\cal N}=1$ SUSY Yang-Mills的退精细相:束缚态和状态方程

The deconfined phase of ${\cal N}=1$ SUSY Yang-Mills: bound states and the equation of state

Gwendolyn Lacroix, Claude Semay, Fabien Buisseret

摘要:

本文在统计力学的$\cal T$ -矩阵公式中研究了${\cal N}=1$超对称Yang-Mills理论在$(3+1)$ -维中的退禁闭相的性质。重点讨论了(1-5)~ $T_c$的温度范围,在这个温度范围内相互作用足够强,可以产生束缚态。对于任何规范群,胶子和胶子的二元束缚态确实被发现束缚到1.4 $T_c$。给出了SU($N$)和$G_2$的状态方程;当归一化到Stefan-Boltzmann压力并表示为$T/T_c$的函数时,发现它几乎与规范群无关,并且非常接近非超对称杨-米尔斯的状态方程。最后,orientifold等价性被证明在状态方程的水平上保持,并且在$N=3$上的精度被证明是非常好的。

英文摘要:

The properties of the deconfined phase of ${\cal N}=1$ supersymmetric Yang-Mills theory in $(3+1)$-dimensions are studied within a $\cal T$-matrix formulation of statistical mechanics in which the medium under study is seen as a gas of quasigluons and quasigluinos interacting nonperturbatively. Emphasis is put on the temperature range (1-5)~$T_c$, where the interaction are expected to be strong enough to generate bound states. Binary bound states of gluons and gluinos are indeed found to be bound up to 1.4 $T_c$ for any gauge group. The equation of state is given for SU($N$) and $G_2$; it is found to be nearly independent of the gauge group and very close to that of non-supersymmetric Yang-Mills when normalized to the Stefan-Boltzmann pressure and expressed as a function of $T/T_c$. Finally the orientifold equivalence is shown to hold at the level of the equation of state and its accuracy at $N=3$ is shown to be very good.
