用高维势模型方法研究重轻介子的Isgur函数

A Higher Dimensional Potential Model Approach in the Study of Isgur-Wise Function for Heavy-Light Mesons

Sabyasachi Roy, D. K. Choudhury

摘要:

玻色弦的南武-后藤作用量预言夸克-反夸克势为$ V (r) = \fracγ{r} + σr +μ_0 $。系数$ γ= - \frac{π(d-2)}{24} $是Lüscher项$ \fracγ{r}$的普适Lüscher系数,它取决于时空维度“d”。以势中的线性项为母体,Lüscher项为微扰,在d维时空中产生介子的波函数,其波函数是Airy无穷多项式级数的形式.利用这个波函数,我们研究了重轻介子及其衍生物的Isgur-Wise函数。

英文摘要:

Nambu-Goto action of bosonic string predicts the quark-antiquark potential to be $ V (r) = \fracγ{r} + σr +μ_0 $. The coefficient$ γ= - \frac{π(d-2)}{24} $ is the universal Lüscher coefficient of the Lüscher term $ \fracγ{r}$, which depends upon the space-time dimension `d'. We take linear term in potential as parent and Lüscher term as perturbation for the generation of wave function for meson in d space-time dimension.The wave function comes out in terms of Airy's infinite polynomial series. With this wave function in higher dimension, we then study the Isgur-Wise function for heavy-light mesons and its derivatives.
