小型地下重子数守恒实验 The Small Underground Experiment of Baryon Number Conservation

在标准模型中重子数是绝对守恒的。 而大统一理论则预言在原子核中的核子将衰变，重子数守恒将被破坏。 本文简要介绍研究核中核子衰变的小型地下实验。 在探测方法技术的改进方面提出了一些新的想法。 The baryon numbers are absolutely conserved in the Standard Model. However, the nucleons in nucleus will decay and baryon-number conservation may not be absolute according to the Grand unified theory. The experimental status of some small underground experiments of baryon number conservation is simply introduced in this paper. A few of improvements of experimental methods and techniques are proposed and discussed.
