论文摘要
我们提出了一个假设,即电子 - 词素对的折叠角分布中的异常,在nucleus $^{8} $ be and $^{4} $的激发水平的衰减中发出,他可以与衰减状态的群集结构有关。此外,我们提出了一个假设,即可能观察到的带有Re st Mass $ M_ {X} $ = 17 MEV可以介导QCD低能状态的核子 - 核子的相互作用,尤其是在弱绑定的群集状态p+$^{7} $ li,$^li,$^3} $ h中。我们提出了一个可能的对称核物质状态方程,与矢量梅森质量$ m_ {v} $ = 17 mEV相对应,使用相对论的核力量平均含量理论获得,尤其是qHD-i,尤其是与物理相关的不合适性k $ _ {0} $ _ {0} $ = 240-260 mev and couplings $ couplings $ couplings $ g_ {团结。基于手性对称性破坏的概念,我们表明,将其余的伪尺度粒子从物理价值$m_π$ = 135 meV减少到$ m_ {x} $ = 17 meV等于减少夸克质量,从310 meV下降到5 mev($ \ frac)($ \ frac}的动态值左右,从310 meV下降到Quark Mose。 {m_ {q,curr}} \ simeq \ frac {m_π^2} {m_ {q,dyn}} $)。戈德伯格 - 特雷曼(Goldberger-Treiman)关系的相应版本导致耦合的值接近核力量相对论平均野战理论的结果。因此,这两种模型方法都表明在核子核子相互作用中的手性对称性明显恢复,这可能是通过反弹到false intenton真空中的。在$^{8} $ be and $^{4} $的衰减中,观察带有休息质量$ m_ {x} $ m_ {x} $ = 17 meV的玻色子。
We present a hypothesis that the anomaly in the folding angle distribution of electron-positron pairs, emitted in the decay of the excited levels of nucleus $^{8}$Be and $^{4}$He can be related to the cluster structure of the decaying state. Furthermore, we present a hypothesis that the potentially observed boson with re st mass $m_{X}$=17 MeV can mediate the nucleon-nucleon interaction at the low-energy regime of QCD, in particular in the weakly bound cluster state p+$^{7}$Li,$^{3}$H. We present a possible equations of state of symmetric nuclear matter corresponding to the vector meson mass $m_{v}$=17 MeV, obtained using relativistic mean field theory of nuclear force, QHD-I in particular, with physically relevant incompessibility K$_{0}$=240-260 MeV and the values of couplings $g_{v}$, $g_{s}$ lower than unity. Based on concepts of chiral symmetry breaking, we show that reduction of the rest mass of pseudoscalar particle from physical value $m_π$=135 MeV to $m_{X}$=17 MeV is equivalent to reduction of the quark mass from dynamical value around 310 MeV down to current quark mass around 5 MeV ($\frac{m_{X}^2} {m_{q,curr}} \simeq \frac{m_π^2} {m_{q,dyn}}$). Corresponding version of Goldberger-Treiman relation leads to the value of coupling close to the results from relativistic mean field theory of nuclear force. Both model approaches thus point towards apparent restoration of chiral symmetry in nucleon-nucleon interaction at large distances, possibly via bounce into false instanton vacuum. Observation of boson with rest mass $m_{X}$=17 MeV in the decay of high lying excited states of $^{8}$Be and $^{4}$He can possibly resolve one of the longest lasting open questions in nuclear physics.
