The most catastrophic man-made phenomena that they are afraid of - and that might be caused by the new accelerator at Franco-Swiss CERN, the Large Hadron Collider - are microscopic black hole production, gigantic strangelets, and the tunneling into another vacuum in the landscape.

他们害怕一台大型强子对撞机会带来有史以来最大的人为灾难：这台加速器可能会产生微型黑洞，巨大的奇异子聚合物，甚至可能导致真空衰变，通过隧穿效应使我们的宇宙衰变到一个能量更低的宇宙中。

The final contribution of gluon-gluon fusion to total cross section can be as large as 5％ of that of quark annihilation because of the large luminosity of gluon in hadron collider.

虽然胶子聚合只有圈图阶的过程，但是由于强子对撞中胶子的高亮度，最终胶子对总过程截面的贡献也可以达到相应夸克贡献的5％。

It is an important topic to analyze the polarization of Λ hyperons produced in deep inelastic scattering because the analysis can provide the mechanism of fragmentation from quark to hadron.

When the proton and neutron collide each other, the hadron emerges from the neutron then trapped between nucleons acting as the strong force medium.

当质子和中子相互碰撞时，强子从中子中溢出充当强力的介质。

Recently the Dyson-Schwinger approach has been a useful tool to study the effects. It has been proven to be successful in developing a hadron phenomenology which interpolates smoothly between the infrared (non-perturbative) and the ultraviolet regime.

最近DS方程的方法已经成为研究动力学手征自发对称性破缺的有效方法，这种方法可以用于微扰问题，也可以用于非微扰问题，可以将红外行为与紫外行为平滑地连接起来。
