We present an estimate of the yield of hard probes expected for collisions of the isobars 4496Ru and 4096Zr at collision energies reachable at RHIC and the LHC. These yields are proportional to the number of binary nucleon-nucleon interactions, which is characteristically different due to the presence of the large neutron skin in 4096Zr. This provides an independent opportunity to measure the difference between the neutron skin of 4496Ru and 4096Zr, which can provide an important constraint on the Equation of State of cold neutron-rich matter.

等压线碰撞中的硬探针作为中子皮探针


我们对等量异位素 4496Ru 和 4096Zr 在 RHIC 和 LHC 可达到的碰撞能量下碰撞的硬探针产量进行了估计。这些产率与二元核子-核子相互作用的数量成正比，由于 4096Zr 中存在大中子皮，其特征是不同的。这提供了测量4496Ru和4096Zr中子皮之间差异的独立机会，这可以为冷富中子物质的状态方程提供重要约束。
