$^3P_0$模型中开粲开底介子的开味强衰变

Open-flavor strong decays of open-charm and open-bottom mesons in the $^3P_0$ model

J. Ferretti, E. Santopinto

摘要:

我们给出了开粲($D$和$D_{\rm s}$)和开底($B$、$B_{\rm s}$和$B_{\rm c}$)介子的开味强衰变的结果。衰变计算的修改版本的$^3P_0$对创建模型,假设谐振子波函数。计算中使用的开粲介子和开底介子的能谱是在Godfrey和Isgur的相对化夸克模型中计算的。还提供了量子数分配。我们的结果与现有的实验数据进行了比较。

英文摘要:

We provide results for the open-flavor strong decays of open-charm ($D$ and $D_{\rm s}$) and open-bottom ($B$, $B_{\rm s}$ and $B_{\rm c}$) mesons. The decays are calculated in a modified version of the $^3P_0$ pair-creation model, assuming harmonic oscillator wave functions. The spectra of open-charm and open-bottom mesons used in the calculations are computed within Godfrey and Isgur's relativized quark model. Quantum number assignments are also provided. Our results are compared with the existing experimental data.
