They are afraid that American researchers will get to see the Higgs boson ahead of them.

他们担心美国研究者会在他们之前看到西格斯介子的玻色子。

They wanted to dispel the rumours that physicists at the Tevatron have been seeing hints of the Higgs boson.

We proposed a model independent approach which is based on isospin and flavor SU (3) symmetry to study charmless B decays.

在B介子无璨弱衰变方面。我们提出了一种模型依赖性较小的分析方法。

We show that the chiral expansionis slowly convergence in vector meson energy region.

We have also shown that our general formula for thepion decay constant 〓 reduces to the well-known Pagels-Stokar formula undercertain approximations.

同时，我们证明了，在一定近似下，可以从我们对π介子衰变常数〓的一般定义推出著名的Pagels-Stokar公式。

We use the same sets of parameters which have been successfully employed in the research of N-N scattering phase shifts and deuteron bound state, to study non-strangeness △△_(3,0)(S = 3,T = 0) and △△_(3,0)(S = 0,T = 3) dibaryons.

利用相同的参数，本文进一步在共振群框架下研究了非奇异的△△_(3，0)(S=3，T=0)和△△_(0，3)(S=0，T=3)双重子束缚态，比较了两种模型下OGE和矢量介子交换贡献。

The DBHF method adopts the realistic nucleon-nucleon interaction, which is fitted to the NN scattering phase shifts and deuteron properties.

G矩阵包含了核子有效相互作用的同位旋信息，同位旋矢量介子对质子和中子的作用不同，在计算中我们区分核物质中的质子和中子，这样得到的RMOP是同位旋相关的。

We use the same sets of paramaters which have been successfully employed in the research of N-N scattering phase shifts and deuteron bound state, to study non-strangeness d* and strangeness S=-3 △Ω(S = 3,T = 3/2) dibaryons.

利用相同的参数，本文在推广的手征SU(3)夸克模型下，应用共振群方法，研究了矢量介子交换效应对非奇异双重子态d~*和奇异夸克数S=-3的ΔΩ(S=3，T=3／2)双重子态的影响。

At first, we introduce in detail relativistic mean-field theory, where a common Lagrangian density is presented. Starting with this Lagrangian density, we can obtain the Dirac equation and Klein-Gordon equations for nucleon and meson field by using Euler-Lagrangian equation.

本文首先详细介绍了相对论平均场理论的一些公式推导，给出了常用的一般的相对论平均场的拉格朗日量，从这个拉氏量出发，利用Euler-Lagrange方程就可导出核子与介子场的运动方程。
