KEKB非对称能量e+e−对撞机的Belle实验积累的大数据样本为研究超子和粲重子提供了机会。我们报告了 Belle 最近对这些主题的测量，包括对新激发 Ω− 和 Ξc 的观察，以及基态 Ξc0 和 Ξc+ 绝对分支分数的首次测量。
The large data sample accumulated by the Belle experiment at KEKB asymmetric energy e+e− collider provides opportunities to study hyperons and charmed baryons. We report recent measurements on these topics from Belle, including observations of new excited Ω− and Ξc, and first measurements of absolute branching fractions for ground states, Ξc0 and Ξc+.
