高能量密度下的强相互作用物质

Strongly Interacting Matter at High Energy Density

Larry McLerran

摘要:

本讲座关注的是在非常高的能量密度下强相互作用物质(由量子色动力学描述)的性质。我回顾了物质在高温下的性质,讨论了解除禁闭的相变。在重子密度高和温度低的情况下,发展了大的$N_c$论证,这表明重子密度高的物质是物质的第三种形式,夸克物质,它不同于受限的强子物质和非受限物质。最后讨论了控制QCD高能极限的色玻璃凝聚体,它形成了强子波函数的低x部分。色球是由彩色玻璃凝聚体形成的物质,最终热化成夸克-胶子等离子体。

英文摘要:

This lecture concerns the properties of strongly interacting matter (which is described by Quantum Chromodynamics) at very high energy density. I review the properties of matter at high temperature, discussing the deconfinement phase transition . At high baryon density and low temperature, large $N_c$ arguments are developed which suggest that high baryonic density matter is a third form of matter, Quarkyonic Matter, that is distinct from confined hadronic matter and deconfined matter. I finally discuss the Color Glass Condensate which controls the high energy limit of QCD, and forms the low x part of a hadron wavefunction. The Glasma is introduced as matter formed by the Color Glass Condensate which eventually thermalizes into a Quark Gluon Plasma.
