STAR中的双电子测量

Dielectron Measurements in STAR

F. Geurts

摘要:

超相对论性重离子碰撞为研究强相互作用物质的性质提供了一个独特的环境。双轻子不受强相互作用的影响,是一种理想的穿透探针。我们提出的双电子的结果为p+p和Au+Au碰撞在$\sqrt{s_\mathrm{NN}}}$ =200 GeV,测量的STAR实验。我们讨论了双轻子测量的前景与不久的将来的检测器升级,和最近的低束能量Au+Au测量。

英文摘要:

Ultrarelativistic heavy-ion collisions provide a unique environment to study the properties of strongly interacting matter. Dileptons, which are not affected by the strong interactions, are an ideal penetrating probe. We present the dielectron results for p+p and Au+Au collisions at $\sqrt{s_\mathrm{NN}}}$ =200 GeV, as measured by the STAR experiment. We discuss the prospects of dilepton measurements with the near-future detector upgrades, and the recent lower beam energy Au+Au measurements.
