论文摘要
最近的调查表明,单句六夸克组合$ uuddss $可能是一个被限制的州$ s $,称为sexaquark。本质上稳定的状态$ S $是潜在的出色的暗物质候选人。我们在$υ(4S)\至λ\barλ$的衰减中首次搜索稳定,双重奇怪的六夸克状态。基于Babar实验收集的$υ(2s)$和$υ(3S)$衰减的数据样本,我们报告了最新结果,并对这种异国情调的粒子的存在设定了严格的限制。
Recent investigations have suggested that the singlet six-quark combination $uuddss$ may be a deeply bound state $S$, called Sexaquark. An essentially stable state $S$ is a potentially excellent Dark Matter candidate. We present the first search for a stable, doubly strange six-quark state in the decays of $Υ(4S) \to Λ\barΛ$. Based on a data sample of $Υ(2S)$ and $Υ(3S)$ decays collected by the BABAR Experiment we report the most recent results and set stringent limits on the existence of such exotic particle.
