Hard probes in isobar collisions as a probe of the neutron skin
Abstract
We present an estimate of the yield of hard probes expected for collisions of the isobars 9644Ru and 9640Zr 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 9640Zr. This provides an independent opportunity to measure the difference between the neutron skin of 9644Ru and 9640Zr, which can provide an important constraint on the Equation of State of cold neutron-rich matter.
