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蒙皮的探针


我们提出了在 RHIC 和 LHC 可达到的碰撞能量下，等压线 4496Ru 和 4096Zr 碰撞的预期硬探针产量的估计值。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，因此其特征不同。这为测量 4496Ru 和 4096Zr 的中子皮层之间的差异提供了一个独立的机会，这可以为富含冷中子物质的状态方程提供重要的约束。
