在重离子碰撞中探测超曲子的尺寸和binding energy

Probing the size and binding energy of the hypertriton in heavy ion collisions

C. A. Bertulani

摘要:

超玻色子的结合能很小(加权平均值约为150 keV),与大物质半径(~ 10 fm)相一致,比35年前发现的历史上的11 Li晕更大。但报道的实验值的结合能的hypertriton范围从70至400 keV。在这项工作中,我讨论的电磁响应和相互作用半径的超triton和如何高能量重离子碰撞(~ 1 - 2 GeV/核子)可以帮助实现更高的精度确定其大小和结合能。

英文摘要:

The hypertriton is predicted to have a small binding energy (a weighted average of about 150 keV), consistent with a large matter radius (~ 10 fm), larger than the historical 11Li halo discovered more than 35 years ago. But the reported experimental values of the binding energy of the hypertriton range from 70 to 400 keV. In this work I discuss the electromagnetic response and interaction radius of the hypertriton and how high energy heavy ion collisions (~ 1 - 2 GeV/nucleon) can help achieving a higher accuracy for the determination of its size and binding energy.
