摘要:
短程关联(SRC)的核-核对是具有高相对动量(prel > kF,其中kF ~ 250 MeV/c是中等至重核中的费米动量)和较低质心动量的核子对。研究SRC对的动机范围从希望更全面地理解高分辨率的多体核波函数到寻找核介质中的显式QCD动力学效应,更不用说与其他许多开放性核物理问题的联系。探索短程关联是建造CEBAF(现为杰斐逊实验室)的物理动机之一。科学家利用该先进机器的高亮度和高能来寻找能清晰显示短程关联信号的动力学。这为过去二十年对这些关联的理解带来了巨大进展。本文回顾了最近的进展,并突显了需要进一步研究的突出问题和领域。
英文摘要:
Short range correlated (SRC) N N pairs are pairs of nucleons with high relative momentum (prel > kF where kF ~ 250 MeV/c is the Fermi momentum in medium to heavy nuclei) and lower center of mass momentum. The motivation for studying SRC pairs ranges from a desire to achieve a more comprehensive understanding of the many-body nuclear wave-function at high-resolution to searching for explicit QCD-dynamics effects within the nuclear medium, not to mention connections to many other open problems in nuclear physics. Exploring short-range correlations was one of the physics motivations for building CEBAF (now Jefferson Lab). Scientists used the high luminosity and high energy of this cutting-edge machine to find kinematics that cleanly showed the signals of short-range correlations. This paved the way in the last two decades for tremendous progress understanding these correlations. This paper reviews recent progress and highlights outstanding questions and areas that need further study.
