到目前为止,大型强子对撞机将质子-反质子对撞机设置的质量限制扩大了两倍,以高达约700千兆电子伏的能量规模高速运作也未能找到任何超夸克的存在。
So far the LHC has doubled the mass limit set by the Tevatron, showing no evidence of squarks at energies up to about 700 gigaelectronvolts.
就好比lord Rutherford证明了原子的存在但不知还有中子,Chadwick不知道夸克的存在一样,更不用说是超对称性了。
Lord Rutherford, who proved that atoms exist, knew nothing of neutrons. Chadwick knew nothing of quarks, let alone supersymmetry.
而随着LHC被设计成重造宇宙早期的环境,物理学家希望能够在原子尘碰撞中寻找超对称夸克和超对称轻子存在的证据。
And since the LHC is designed to recreate conditions in the early universe, physicists hope to see evidence of squarks and sleptons in the fallout from those collisions.
发现规范对称自发破缺和超对称破缺是可以实现的,但在夸克轻子质量问题上遇到困难。
We find that the spontaneous breaking of gauge symmetry and supersymmetry can be realized, but it is difficult to make the quarks and leptons to acquire small masses.
M理论预测了超对称性的存在,超对称性认为所有基本粒子都存在伴粒子,这些伴粒子的名称都很奇特,比如超对称电子(selectrons)和超对称夸克(squarks)等,但到目前为止,科学家们还没有发现这种超对称性伴粒子。
One possibility predicted by M-theory is supersymmetry, an idea that says fundamental particles have heavy – and as yet undiscovered – twins, with curious names such as selectrons and squarks.
这样自然得到了分数电荷、超荷的夸克相干态。
In this way, the fractionally charged, hypercharged quark states can be obtained naturally.
其实对称性动力学破缺可以解决希格斯机制带来的很多问题,比如超对称和夸克禁闭等问题。
In fact, Dynamic symmetry violation can solve many problems which arising Higgs mechanism, such as super symmetry and quark confinement and other issues.
我们这里研究了混合相物质的体粘滞系数,计算了两类非轻子过程(超子和夸克非轻子衰变)对混合相粘滞性的贡献。
Here we study the coefficient of viscosity in mixed phases, calculate the contributions of two kinds of non-leptonic reactions (the non-leptonic decay of hyperons and quarks).
