相对论模型中的重轻介子

Heavy-Light Mesons In A Relativistic Model

Jing-Bin Liu, Mao-Zhi Yang

摘要:

我们在相对论模型中研究了重-轻介子,该模型是由瞬时Bethe-Salpeter方程通过重夸克的Foldy-Wouthuysen变换导出的。我们选择的核是基于标量束缚势和矢量库仑势,在这个模型中还考虑了胶子交换的横向相互作用。计算了$D$,$D_s$,$B$,$B_s$介子态的能谱和波函数.计算的谱达到$1/m_Q$阶,波函数被处理到首阶。

英文摘要:

We study the heavy-light mesons in a relativistic model, which is derived from the instantaneous Bethe-Salpeter equation by applying the Foldy-Wouthuysen transformation on the heavy quark. The kernel we choose is based on scalar confining and vector Coulomb potentials, the transverse interaction of the gluon exchange is also taken into account in this model. The spectra and wave functions of $D$, $D_s$, $B$, $B_s$ meson states are obtained. The spectra are calculated up to the order of $1/m_Q$, and wave functions are treated to leading order.
