具有瞬子诱导相互作用的相对论模型中P波介子谱

P Wave Meson Spectrum in a Relativistic Model with Instanton Induced Interaction

Bhavyashri, K. B. Vijaya Kumar, Yong-Liang Ma, Antony Prakash

摘要:

在夸克唯象相对论谐振模型的基础上,我们得到了P波介子的质量。在研究中使用的完整的哈密顿量有洛伦兹标量+矢量禁闭势,以及一个胶子交换势(OGEP)和瞬子诱导的夸克-反夸克相互作用(III)。与实验质量得到了很好的一致性。III和OGEP的介子质量的测定各自的作用进行了讨论。

英文摘要:

On the basis of the phenomenological relativistic harmonic models for quarks we have obtained the masses of P wave mesons. The full Hamiltonian used in the investigation has Lorentz scalar + vector confinement potential, along with one gluon exchange potential (OGEP) and the instanton-induced quark-antiquark interaction (III). A good agreement is obtained with the experimental masses. The respective role of III and OGEP for the determination of the meson masses is discussed.
