论文摘要
我们预测,使用与风味相关的互动模式,使用统一的成功描述了轻,重型的Mesons,并且对Radial兴奋的重型Mesons适应了统一的成功描述。错误是仔细控制的。随着RL近似所述的错误,我们的预测与LQCD和Quark模型结果一致,这强烈支持依赖风味的相互作用模式是合理的。我们的预测为$ b_c $梅森的实验搜索提供了重要的指南。
We predict the masses of the lowlying $B_c$ mesons with $J^P = 0^-,\,1^-,\,0^+,\,1^+,\,2^+$, using a flavor dependent interaction pattern which gives an unified successful description of the light, heavy-light and heavy mesons and is also appliable to the radial excited heavy mesons. The errors are controlled carefully. With the errors from the RL approximation subduced, our predictions are consistent with the lQCD and quark model results, which supports strongly that the flavor dependent interaction pattern is reasonable. Our predictions provide significant guides to the experiment search of the $B_c$ mesons.
