讨论了MSSM中精密量规的统一问题。我们发现，一个相对较轻的胶子，当它出现在某些软超对称破缺模式时，可以成为确保精确规范统一的关键因素，而不依赖于大统一尺度周围额外粒子的存在。特别是，所谓的高规质量的海市蜃楼模式可以自然地导致精确的标准统一。由于相当轻的胶子，还存在与减少微调的有趣关联。
We discuss the issue of precision gauge unification in the MSSM. We find that a comparably light gluino, as it emerges in certain patterns of soft supersymmetry breaking, can be a key ingredient for ensuring precision gauge unification without relying on the presence of extra particles around the scale of grand unification. In particular, the so-called mirage pattern for gaugino masses can naturally lead to precision gauge unification. There is also an interesting correlation with reduced fine-tuning, due to rather light gluinos.
