论文摘要
在Dibaryon诱导的$ NN $相互作用的模型中，$ PP $ scationing in $ p $ waves中的散布主要由中间二巴里亚族共振的产生支配。证明了两次由Anke-Cosy合作发现的质量约为2200 MEV的Dibaryon共振，旨在确定$^3p_0 $和$^3p_2 $ - $^3F_2 $ - $^3F_2 $ CHANNELS中的Elastic $ PP $相位偏移和非弹性，从零能量从零能源到$ t_p = 0.7 $ $ - $ 0.9 $ 0.9 $ 0.9 $ 0.9 $ 0.9 $ 0.9 $ 0.9 $ 0.9 $ 0.9 $ 0.9。还清楚地表明，$^3p_0 $ dibaryon在$ pp $碰撞中近距离中性锥子的生产中起着决定性的作用，迄今为止鲜为人知。发现缺失的二巴里亚贡献是传统方法未能解释接近阈值$π^0 $生产的可能原因。
It is demonstrated within the dibaryon-induced model for $NN$ interaction that $pp$ scattering in $P$ waves is governed mainly by the production of the intermediate dibaryon resonances. Two dibaryon resonances with a mass of about 2200 MeV discovered recently by the ANKE-COSY Collaboration are shown to determine both elastic $pp$ phase shifts and inelasticities in the $^3P_0$ and $^3P_2$-$^3F_2$ channels from zero energy up to $T_p=0.7$-$0.9$ GeV. It is also demonstrated clearly that the $^3P_0$ dibaryon plays a decisive role in near-threshold neutral pion production in $pp$ collisions which is poorly understood to date. The missing dibaryon contribution is found to be the very possible reason for the failure of traditional approaches to explain near-threshold $π^0$ production.
