我们研究了1GeV/c动量K介子束作用于核上的（K，p）反应，特别关注动能大于600 MeV的质子发射区域，该区域被用来描述K介子核的光学势。我们的模型描述了核反应的局部密度方法的框架和计算进行以下两个不同的程序：一个是基于使用Lindhard函数的多体方法，另一个是基于Monte Carlo模拟。模拟方法提供了灵活性，以考虑K介子准弹性散射以外的过程，如产生超子的一个和两个核子的K吸收，并允许考虑K，p和所有其他初级和次级粒子在离开粒子的途中的终态相互作用。
We study the (K ,p) reaction on nuclei with a 1 GeV/c momentum kaon beam, paying a special attention at the region of emitted protons having kinetic energy above 600 MeV, which was used to claim a deeply attractive kaon nucleus optical potential. Our model describes the nuclear reaction in the framework of a local density approach and the calculations are performed following two different procedures: one is based on a many-body method using the Lindhard function and the other one is based on a Monte Carlo simulation. The simulation method offers flexibility to account for processes other than kaon quasi-elastic scattering, like K absorption by one and two nucleons producing hyperons, and allows to consider final state interactions of the K , p and all other primary and secondary particles on their way out of the ¯
