多夸克奇异强子的少体研究

Few-body insights of multiquark exotic hadrons

Javier Vijande, Jean-Marc Richard, Alfredo Valcarce

摘要:

在这方面的贡献,我们讨论了充分的治疗$4-$和$5-$体动力学的组成夸克框架内。我们强调,变分近似和玻恩-奥本海默近似给出的能量相当接近精确的能量,而双夸克近似可能是相当误导。霍尔-波斯特不等式提供了非常有用的下界,排除了某些质量比和色波函数的可能稳定状态。

英文摘要:

In this contribution we discuss the adequate treatment of the $4-$ and $5-$body dynamics within a constituent quark framework. We stress that the variational and Born-Oppenheimer approximations give energies rather close to the exact ones, while the diquark approximation might be rather misleading. Hall-Post inequalities provide very useful lower bounds that exclude possible stable states for some mass ratios and color wave functions.
