论文摘要
我们使用扩散的蒙特卡洛技术来描述完全沉重的紧凑型布置（无二豆分子）的特性，其中包括六个夸克和没有组成夸克模型的框架中的架子。仅考虑了其波形的特征向量，其特征向量为$ l^2 $，并考虑了特征值$ \ ell $ = 0，这意味着我们仅考虑了所有可能的颜色组合的子集，这些组合使总波形抗对称相对于同一类型的任何两种夸克的交换。这意味着$ cccccc $，$ bbbbbb $，$ cccccb $，$ bbbbbbc $和$ bbbbbc $和$ cccbbbb $和spin $ s = 0,1,2 $ for $ cccccc $，$ bbbbbbb $，$ bbbbbbb $，$ bbbbbbb $，$ bbbbbbb $，$ bbbbbbb $，$ bbbbbbb $，$ bbbbbbb $，$ ccccbb $和$ cccccbbb $和$ bbbbbcc $ hexaquarks的安排。在所有情况下，六夸克排列的质量都比我们可以将它们分成的两个重子的总和对应的质量更大，但是较小的是，六个隔离夸克的质量是较小的，即所有这些夸大的夸克，即，它们都是绑定的系统。对其结构的分析表明，除$ CCCBBB $外，这项工作中考虑的所有六夸克人都是紧凑的对象，似乎是两个重子的宽松关联。
We used a diffusion Monte Carlo technique to describe the properties of fully-heavy compact arrangements (no dibaryon molecules) including six quarks and no antiquarks within the framewok of a constituent quark model. Only arrangements whose wavefunctions were eigenvectors of $L^2$ with eigenvalue $\ell$ = 0 were taken into account, what means that we only considered the subset of all the possible color-spin combinations that make the total wavefunctions antisymmetric with respect to the interchange of any two quarks of the same type. This means arrangements with spin $S=0$ for $cccccc$, $bbbbbb$, $cccccb$, $bbbbbc$ and $cccbbb$ and spin $S=0,1,2$ for the $ccccbb$ and $bbbbcc$ hexaquarks. In all cases, the masses of the six-quark arrangements are larger that the ones corresponding to the sum of any of the two baryons we can split them into, but smaller that the ones for a set of six isolated quarks, i.e., all them are bound systems. The analysis of their structure indicates that all the hexaquarks considered in this work are compact objects, except the $cccbbb$, that appears to be a loose association of two baryons.
