有限温度下快子物质的(去)禁闭跃迁

The (de)-confinement transition in tachyonic matter at finite temperature

Adamu Issifu, Francisco A. Brito

摘要:

在本文中,我们提出了一个模拟QCD理论的QCD激发模型。我们研究了在温度($T$)存在下,与色介电函数($G$)耦合的规范场的特性。目标是在低温下实现对$T<T_{c}$($T_{c}$是临界温度)的限制,类似于低能强子中夸克和胶子之间发生的情况。另外,我们还研究了标量胶球和QCD弦张力以及温度对它们的影响。为了实现这一点,我们使用的现象,颜色介电函数的规范场在一个缓慢变化的快子介质。该方法适用于分析计算所产生的潜在的,胶球质量和弦张力与限制在有限的温度。我们表明,颜色介电函数改变麦克斯韦方程作为快子场的函数,并诱导电场的方式,在快子凝聚过程中的临界温度以下带来的限制。

英文摘要:

In this paper we present a QCD motivated model that mimics QCD theory. We examine the characteristics of the gauge field coupled with the color dielectric function ($G$) in the presence of temperature ($T$). The aim is to achieve confinement at low temperatures $T<T_{c}$, ($T_{c}$, is the critical temperature), similar to what occurs among quarks and gluons in hadrons at low energies. Also, we investigate scalar glueballs and QCD string tension and effect of temperature on them. To achieve this, we use the phenomenon of color dielectric function in gauge fields in a slowly varying tachyon medium. This method is suitable for analytically computing the resulting potential, glueball masses and the string tension associated with the confinement at a finite temperature. We demonstrate that the color dielectric function changes Maxwell's equation as a function of the tachyon fields and induces the electric field in a way that brings about confinement during the tachyon condensation below the critical temperature.
