强子

Similar to Debye screening in QED, at sufficiently high density we expect colour screening to set in and the potential does not go into infinity as r increases. Color screening thus transform a color insulator into a color conductor, turning hadronic matter into a quark matter, where the interactions between quarks and gluons become relatively weak and long range.

在极高的能量密度下，类似于量子电动力学中的"德拜屏蔽"，夸克、胶子间的相互作用可能不再随距离的增大而趋于无穷大，夸克、胶子可以超出强子，在较大的范围内运动，形成夸克-胶子等离子体。

In addition, we introduce the current status of the light meson spectroscopy and the new hadronic states lying beyond the quark model.

此外，我们简要介绍了轻介子谱的研究现状以及新强子态—胶球和混杂态。

Comparing the results obtained from the method of renormalization and of the form factors, one finds that if we adjust the parameters, it is possible to make the two sets approach each other better.

我们把用这种方法得到的结果与重整化的结果比较，发现在计算强子传播子时，这两种方法的数值结果近似。

In this thesis, we give a review on RMF model systematically. Combining the quake effort on the meson field introduced by Quantum meson coupling model, we reconstruct the RMF model and investigate the basic property of some nuclei.

本文首先介绍了量子强子动力学理论，这个理论是在很多地方都有成功的应用，在 QHD 基础上，引入了考虑核内结构的夸克介子耦合模型，借鉴 QMC 中对夸克介子的成功耦合，本文改进相对论平均场理论，使其更精确的计算锂等原子核的基态性质，研究中子晕等现象。

We revisted the process B→η＇K and got the same result as the previous literature that the experient data is 2-4 times larger than the theoretical calculation We calculated the matrix element of scalar and tensor operators, which can be applied in some models beyond Stand Models, such as Minimal Super-Symmetry Models.

我们还在BBNS因子化方案下计算了某些新的算符，例如标量算符，张量算符等的强子矩阵元，这一结果可以应用到标准模型扩展如最小超对称模型中，计算新物理的贡献。

The toy in question was the Large Hadron Collider, and it was going to find all sorts of wonderful things, ranging from the Higgs boson (which is needed to explain why mass exists in the first place) via dark matter (which is needed to explain why the universe is as massive as it is) to miniature black holes the densest concentrations of mass possible, which journalists of a more scaremongering disposition confidently predicted would eat the Earth up as soon as the machine was switched on

被大家津津乐道的新玩意是大型强子对撞机，它将揭示各种奇妙的事情，从通过暗物质（解释宇宙为什么如此浩瀚）寻找希格斯玻色子（是用来解释质量起初存在的原因）到寻找小型黑洞（可能的最密集质量的聚集物，一些危言耸听的记者信誓旦旦地散布谣言一旦大型机开启，地球将迅速被吞没）。

这一热议中的玩物便是大型强子对撞机，从希格斯玻色子（用于解释为何会有质量的存在）到暗物质（用于解释为何宇宙会膨胀得如此浩大）再到迷你黑洞（宇宙间可能存在的密度最大的事物，一些好煽动的新闻记者曾自信地预言随着该对撞机的启动，迷你黑洞将吞灭整个地球），LHC被赋予了寻找到各种美妙事物的厚望。

The spectral curve vs invariant mass is becoming wider and the peak is shifted towards the high invariant mass region with the increase of temperature. However, in ultra high temperature or density envi- ronment, the peak is shifted towards lower region and the curve is changed narrower with the increase of temperature. In the invariant mass region M 憕.-?0.4 GeV?.6 Ge1~, the spectral function is enhanced very much. which contributes to the interpretation of dilepton enhancement results in relevant experi

结果显示高温高密强子物质环境对其有非常重要的影响：ρ谱函数在温度或密度不太高时谱函数曲线变宽，并且峰朝不变质量高的方向移动；在极端高温或高密情况下谱函数却变窄，并且峰朝不变质量低的方向移动，在不变质量M～0.4-0.6 GeV区间谱函数有比较明显的增强，这有助于解释双轻子产生的相关实验现象。
