摘要

欧洲核子研究中心sps的NA60实验研究质子-核和重离子碰撞中的介子产生。我们报道了在铟-铟碰撞中测量开放粲数的努力。虽然最后的背景减法程序的工作仍在进行中，但我们已经可以证明探测器的性能足以区分来自遥远\(D\bar D\)衰变的提示子对和介子对。

Measuring Displaced muon Pairs in Indium-Indium collisions at the CERN SPS

The NA60 experiment at the CERN-SPS studies dimuon production in proton-nucleus and heavy-ion collisions. We report on the effort towards measuring open charm in Indium-Indium collisions. Although work on the final background subtraction procedure is still under way, we can already demonstrate that the detector performance is adequate to separate prompt dimuous from muon pairs originating in distant \(D\bar D\) decays.
