$B$介子的密度分布

Density distributions in the $B$ meson

Benoît Blossier, Antoine Gérardin

摘要:

利用双味格格点量子色动力学方法研究了$B$介子的轴向、电荷和物质分布及其第一径向激发。由于我们的框架是重夸克有效理论(HQET)的静态极限,采取他们的傅里叶变换提供了在运动学点$q^2=0$访问几个形状因子。此外,它们还提供了一些关于激发态,即夸克-反夸克束缚态或多强子态的径向激发的性质的有用信息。

英文摘要:

We report on a two-flavor lattice QCD study of the axial, charge and matter distributions of the $B$ meson and its first radial excitation. As our framework is the static limit of Heavy Quark Effective Theory (HQET), taking their Fourier transform gives access to several form factors at the kinematical point $q^2=0$. Moreover they provide some useful information on the nature of an excited state, i.e. a radial excitation of a quark-antiquark bound state or a multihadron state.
