重味二重子

Very heavy flavored dibaryons

Jean-Marc Richard, Alfredo Valcarce, Javier Vijande

摘要:

我们用一个能在重夸克构成的强子极限下得到正确解的组分模型,探讨了含有三个魅夸克和三个美夸克的超重双重子$bbbccc$的可能性.六体问题被严格对待,特别是考虑到轨道,颜色和自旋混合对称分量的波函数。与最近基于格点量子色动力学的声明不同,在最低解离阈值以下没有发现束缚态。

英文摘要:

We explore the possibility of very heavy dibaryons with three charm quarks and three beauty quarks, $bbbccc$, using a constituent model which should drive to the correct solution in the limit of hadrons made of heavy quarks. The six-body problem is treated rigorously, in particular taking into account the orbital, color and spin mixed-symmetry components of the wave function. Unlike a recent claim based on lattice QCD, no bound state is found below the lowest dissociation threshold.
