光矢量介子
Light Vector Mesons
摘要：
本文综述了质子-质子和重离子碰撞中产生的轻矢量介子的测量实验现状。本文着重介绍了与轻矢量介子有关的两种现象：为寻求手征对称性恢复而对谱形的修改和重离子碰撞中介子产生的抑制。实验结果表明，与真空中测量的参数相比，光矢量介子的光谱形状得到了修正。改性的性质和大小取决于产生它们的介质的能量密度。光矢量介子的抑制模式不同于其它介子和重子的测量。介子被抑制的机制尚不清楚。对现有实验结果的系统比较指出了缺失的数据，这可能有助于解决问题。
英文摘要：
This article reviews the current status of experimental results obtained in the measurement of light vector mesons produced in proton-proton and heavy ion collisions at different energies. The review is focused on two phenomena related to the light vector mesons; the modification of the spectral shape in search of Chiral symmetry restoration and suppression of the meson production in heavy ion collisions. The experimental results show that the spectral shape of light vector mesons are modified compared to the parameters measured in vacuum. The nature and the magnitude of the modification depends on the energy density of the media in which they are produced. The suppression patterns of light vector mesons are different from the measurements of other mesons and baryons. The mechanisms responsible for the suppression of the mesons are not yet understood. Systematic comparison of existing experimental results points to the missing data which may help to resolve the problem.
