摘要

光学模型势(OMP)是基础和应用核物理的关键要素。当今的计算能力使我们能够生成数据驱动的核子-核光学模型势,这些模型势具有非局部性和精确分散性(正如理论上所要求的那样),包括统计上合理的不确定性量化,并根据来自核图广泛区域的散射和束缚态数据进行训练。这些特点结合在一起,大大提高了模型的保真度和外推能力。在此,我们介绍了开发和训练这种 OMP 的初步工作。该模型在第一阶段描述数据的能力令人鼓舞。

Towards next-generation optical potentials for nuclear reactions and structure calculations
Optical-model potentials (OMPs) are critical ingredients for basic and applied nuclear physics. Present-day computational capabilities allow us to generate data-driven nucleon-nucleus OMPs that are non-local and exactly dispersive (as theoretically required to be), include statistically-sound uncertainty quantification, and are trained on both scattering and bound-state data from a wide area of the nuclear chart. Combined together, these features allow for significant improvement in fidelity and extrapolative power of the model. Here, we present preliminary work toward the development and training of such an OMP. The capability of the model to describe data at this first stage is encouraging.
