摘要

利用非相对论夸克模型（NRQM）获得了Bc介子态的质谱。非相对论性夸克模型的框架由摄动单胶子交换的类库仑势和线性约束势以及由瞬子真空导出的势组成。通过对（J,M2）和（nr,M2）平面上绘制的雷格轨迹的评价，得到了与实验质量基本一致的结果。

Study of mass spectra and Regge trajectories of Bc mesons with instanton induced potential in NRQM

The mass spectrum of

B_{c}

meson states is obtained using a phenomenological non-relativistic quark model (NRQM). The framework of the non relativistic quark model consists of a Coulomb like potential from the perturbative one gluon exchange and the linear confining potential along with the potential derived from instanton vacuum. An overall agreement is obtained with the experimental masses and results are justified by the evaluation of the regge trajectories plotted in the (J,

M^{2}

) and (

n_{r}

M^{2}

) planes.
