标题： Nuclear beams in HERA

摘要： 研究了HERA中核束实验的物理兴趣和可行性。结果表明，与自由核子靶标相比，这类实验极大地拓宽了探测QCD的视野。此外，对标准模型之外的物理也具有一些敏感性。因此，在HERA中引入循环核束这一选择使得可以研究和理解广泛的物理过程。 显示英文摘要

摘要： A study has been made of the physics interest and feasibility of experiments with nuclear beams in HERA. It is shown that such experiments widen considerably the horizon for probing QCD compared to that from free nucleon targets. In addition there is some sensitivity to physics beyond the standard model. Hence the option to include circulating nuclear beams in HERA allows a wide range of physics processes to be studied and understood.
