$\bar B_s$介子的弱衰变

Weak decays of $\bar B_s$ mesons

C. Albertus

摘要:

本文在非相对论组分夸克模型下研究了$\bar B_s$介子的半轻子衰变。我们用不同的夸克间势来计算介子波函数,并估计了计算的不确定性。在无限重夸克质量的极限下,我们将我们模型的结果与重夸克对称性的预测进行了检验。我们还在因子化近似下研究了$\bar B_s$介子的非轻子衰变。

英文摘要:

In the present work we study the semileptonic decays of $\bar B_s$ mesons in the context of nonrelativistic constituent quark models. We estimate the uncertainties of our calculation using different interquark potentials to obtain the meson wave functions. We check the results from our model against the predictions of Heavy Quark Symmetry, in the limit of infinite heavy quark mass. We also study the nonleptonic decays of $\bar B_s$ mesons within the factorization approximation.
