ALICE是欧洲核子研究中心（CERN）大型强子对撞机（LHC）专门研究高能核对核碰撞的实验。它出色的粒子识别能力允许测量很少产生的粒子，如超核和轻核（及其反粒子）。本文给出了在每核子-核子对质量能量中心TeV处Pb-Pb碰撞的结果。特别讨论了和的测量。此外，还介绍了（反）高氚子通过介子衰变的重建。搜索更轻的超物质状态，即ΛΛ（也称为h -双重子）和Λn束缚态，进行了讨论。结果与热模型预测结果进行了比较。
ALICE is the experiment at the CERN LHC dedicated to the investigation of high energy nucleus–nucleus collisions. Its excellent particle identification capabilities allow for the measurement of rarely produced particles, like hypernuclei and light nuclei (and their anti-particles). We present here results from Pb–Pb collisions at a center of mass energy of TeV per nucleon-nucleon pair. In particular the measurement of and is discussed. In addition the reconstruction of (anti-)hypertritons via their mesonic decay is presented. Searches for even lighter hypermatter states, i.e. ΛΛ (also known as H-Dibaryon) and Λn bound states, are dicussed. The results are compared with thermal model predictions.
