重子Δ的质量

摘要

在最新的粒子表中，带负电荷的Δ－仍然没有实验数据，Δ0、Δ＋、Δ＋＋的质量没有可信的测量数据，只有混合的带电Δ的质量测量是可信的。本文先给出重子十重态Δ、Σ倡、Ξ倡、Ω之间的质量关系，再计算四个Δ重子的质量。最后结合实验数据进行了讨论。文章结果对于精确研究重子Δ的质量有一定的参考意义。未来可以在LHC等实验装置中验证。%According to the recent version of “Review of Particle Physics”.There are no data for the negative charged baryon Δ-.There are no reliable data for the three baryons Δ++, Δ+, and Δ0 .Mass relations of the baryon decuplet (Δ,Σ,Ξ, Ω) are given.After that, masses of the four Δbaryons are calculated.Based on the experiment data, the results are discussed.The predictions may be useful guidance for the precious measurement of the Δbaryons.The results can be tested at LHC in the near future.
