标题： Parity-violating longitudinal response

摘要： 纵向准弹性宇称破坏电子散射响应在构建于相对论费米气体基础上的对称化RPA-HF相关性的模型中进行了研究。 这种可观测量对核动力学的高敏感性，在之前仅包含介子相关性的研究中被发现，在当前模型中，当考虑到一种版本的博恩势中的介子、rho、sigma和omega交换效应时，这种敏感性仍然存在。 通过一个复杂的图示抵消/过滤机制，纵向宇称破坏响应结果与仅考虑介子的一阶微扰理论结果非常接近。 最后，与我们之前的工作一致，宇称破坏响应显示出对核子电奇素含量的显著敏感性，尤其是在高动量转移情况下。 显示英文摘要

摘要： The longitudinal quasielastic parity-violating electron scattering response is explored within the context of a model that builds antisymmetrized RPA-HF correlations on a relativistic Fermi gas basis. The large sensitivity to nuclear dynamics of this observable, found in previous studies where only pionic correlations were included, is shown to survive in the present model where the effects from pion, rho, sigma and omega exchange in a version of the Bonn potential are incorporated. Through an intricate diagrammatic cancellation/filtration mechanism the longitudinal parity-violating response turns out to be close to the one obtained in first-order perturbation theory with the pion alone. Finally, in accord with our previous work, the parity-violating response is seen to display appreciable sensitivity to the electric strangeness content of the nucleon, especially at high momentum transfer.
