论文摘要
SU（3）YANG-MILLS理论的状态方程可以通过有效的$ Z_3- $对称电位$ V（\ Vertϕ \ vert，ϕ^3+ϕ^{3*}，t），根据温度$ t $，并在标量field $ - ϕ $ - ϕ $ - deveraged polopolakov loop上。允许$ ϕ $动态性为研究Polyakov环的空间局部经典配置开辟了道路。我们首先表明，球形对称静态Q-balls存在于$（1-1.21）\ times t_c $，$ t_c $是反登录温度的范围内。然后，我们认为Q-Holes解决方案，如果我们的框架内有任何杂物。最后，我们将Polyakov-loop Lagrangian与Einstein重力息息结合，并表明球形对称的静态玻色子星存在在相同的温度范围内。我们发现的Q-Ball和Boson Star溶液可以解释为脱合性gluonic物质的“气泡”。它们的平均半径总是小于10 FM。
The equation of state of SU(3) Yang-Mills theory can be modelled by an effective $Z_3-$symmetric potential $V(\vertϕ\vert,ϕ^3+ϕ^{3*}, T)$ depending on the temperature $T$ and on a scalar field $ϕ$ -- the averaged Polyakov loop. Allowing $ϕ$ to be dynamical opens the way to the study of spatially localized classical configurations of the Polyakov loop. We first show that spherically symmetric static Q-balls exist in the range $(1-1.21)\times T_c$, $T_c$ being the deconfinement temperature. Then we argue that Q-holes solutions, if any are unphysical within our framework. Finally we couple the Polyakov-loop Lagrangian to Einstein gravity and show that spherically symmetric static boson stars exist in the same range of temperature. The Q-ball and boson star solutions we find can be interpreted as "bubbles" of deconfined gluonic matter; their mean radius is always smaller than 10 fm.
