查询词典 hadrons

Understanding the structures of hadrons, finding the physics of how the properties of these particles arise from the first principle, are major interests in modern nuclear physics.

弄清这些强子的结构，并由基本原理出发研究它们的性质，是当代核物理的重要课题。

Even though in QCD we have a theory of the strong interactions, unfortunately, calculating the properties of hadrons from the QCD lagrangian has proven to be a very difficult task in this strongly coupled nonlinear theory.

由于QCD是一个非线性的、非常复杂的理论，而且强子内部的相互作用很强，所以从QCD拉式量出发计算强子的性质是一个非常艰巨的任务。

By this means the transition between partons and hadrons is a parton-wise behavior instead of a collective one, resulting in individual hadronization time of partons.

这种办法使得部分子到强子之间的转变成为单个部分子的个体行为，而不是整个系统的集体行为。

Although the Tevatron produces many orders of magnitude more hadrons than do the machines at KEK and SLAC, it is nevertheless much harder to study the decay of B mesons in proton-antiproton collisions.

虽然Tevatron能比KEK和SLAC的加速器产生多许多个数量级的强子，但是在正负质子的碰撞中研究B介子的衰变仍是非常困难的。

At the same time, this paper annaylses the particle-detector interaction and the detector response. The behaviors of electrons, photons and hadrons in EEMC are studied and they are also compared with the rusults in barrel electromagnetic calorimeter. Also, the calculation and realization method of standard electromagnetic interaction is compared with the low electromagnetic interaction.

同时，分析粒子与探测器相互作用及探测器的响应处理，分析电子、光子和强子在端盖量能器的行为，与桶部量能器的模拟结果进行对比研究，并对低能电磁相互作用和标准电磁住作用的计算方法和实现方法进行了比较。

In the last half century, many theoretical and experimental envidences confirmed the existence of quarks without doubt, however, these experiments showed that quarks only exist inside hadrons and we will never find free quark.

近半个世纪的理论和实验研究无可争辩地证实了核子等强子内存在夸克，不过这些夸克只存在于核子等强子内而不能作为自由夸克存在。

The investigation of the dibaryon can also make further test of the quark models which have successfully described the properties of the hadrons. Therefore, The study of dibaryon will supply a wider realm to understand and test QCD.

双重子的研究可以进一步检验在强子性质描述上取得成功的夸克模型，让我们在更广阔的领域内了解甚至检验QCD。

Quarks that make the quantum number of hadrons are named 'valence quarks'.

构成强子的量子数的夸克，称为价夸克valence quarks。

A charged-current event gives a muon plus hadrons: a long charged track from the muon, which is easy to find.

通过收费电流宣布事件给出了μ子加强子：一个长期负责跟踪从介子，这是不太容易找到。
