束缚反质子-核系统的动力学模拟和冷核压缩的可观测信号
Dynamical simulation of bound antiproton-nuclear systems and observable signals of cold nuclear compression
摘要：
本文在自洽相对论平均场作用于重子和反重子的动力学方程的基础上，研究了注入反质子后原子核的动力学响应。通过数值求解含时的Vlasov方程，我们发现压缩态是在4-10 fm/c的相当短的时间尺度上形成的。这证明了反质子湮灭可能发生在压缩核环境中的假设。反质子湮灭后原子核的演化也可用同样的动力学方程描述。我们指出，核子动能谱和产生介子的总不变质量分布是对压缩核中反质子湮灭相当敏感的观测量。
英文摘要：
On the basis of the kinetic equation with selfconsistent relativistic mean fields acting on baryons and antibaryons, we study dynamical response of the nucleus to an antiproton implanted in its interior. By solving numerically the time-dependent Vlasov equation, we show that the compressed state is formed on a rather short time scale of about 4-10 fm/c. This justifies the assumption, that the antiproton annihilation may happen in the compressed nuclear environment. The evolution of the nucleus after antiproton annihilation is described by the same kinetic equation including collision terms. We show, that nucleon kinetic energy spectra and the total invariant mass distributions of produced mesons are quite sensitive observables to the antiproton annihilation in the compressed nucleus.
