论文摘要
在这项工作中，我们提出了一种测量不同同位素之间中子皮肤厚度演变的新方法。我们认为接近$λ\Overlineλ$和$σ\Overlineλ$ Pairs的生产阈值接近的抗蛋白质 - 核核相互作用。在低能量时，$λ\叠加λ$对在P + P碰撞中产生，而$σ\Overlineλ$对只能在P + N相互作用中产生。测量这些横截面可提供有关中子皮肤厚度的信息
In this work we propose a new method to measure the evolution of the neutron skin thickness between different isotopes. We consider antiproton-nucleus interactions close to the production threshold of $Λ\overlineΛ$ and $Σ\overlineΛ$ pairs. At low energies, $Λ\overlineΛ$ pairs are produced in p + p collisions, while $Σ\overlineΛ$ pairs can only be produced in p + n interactions. Measuring these cross sections provides information on the neutron skin thickness
