具有隐底的标量四夸克的质量和宽度

Masses and widths of scalar tetraquarks with hidden bottom

S. M. Gerasyuta, V. I. Kochkin

摘要:

在耦合道形式主义的框架下得到了相对论性四夸克方程。研究了介子-介子态与四夸克态的动力学混合。构造了包含u、d、s和底夸克的隐底四夸克态的四夸克振幅。这些振幅的极点决定了四夸克的质量和宽度。

英文摘要:

The relativistic four-quark equations are found in the framework of coupled-channel formalism. The dynamical mixing of the meson-meson states with the four-quark states is considered. The four-quark amplitudes of the tetraquarks with hidden bottom, including u, d, s and bottom quarks, are constructed. The poles of these amplitudes determine the masses and widths of tetraquarks.
