反质子与质子相互作用

Antiproton—Proton Interaction

本文论述从低能至高能的反质子与质子碰撞中各种现象,从介子交换理论和吸收现象,获得一个可以描述其相互作用的光学势。pp碰撞后,发生湮没而产生众多的介子、强子,以及在高能正、反质子湮没后产生奇特性粒子,带粲的介子、强子,并探讨获得混杂性粒子和新粒子的途径。

In this paper is discussed several phenomena of antiproton—proton collision from low to high antiproton energy range. From meson exchange theory and absorption phenomenon, an optical potential can be obtained which can be used to describe pp scattering process. The annihilation that occurs after pp collision produces many kinds of meson and hadron, and even produces some exotic particles and charmonium at high energy antiproton—proton annihilation. Also, the posibilities to find hybrids (qqg) and multiquark particles are explored.
