查询词典 neutral meson

The CDF physicists measured the rate of matter-antimatter transitions for the neutral Bs meson, a particle composed of a "bottom" quark and a "strange" antiquark.

CDF的物理学家们测量了中性Bs介子（一种由一个底夸克和一个奇夸克构成的粒子）的物质-反物质转变速率。

In the "indirect" process, first observed in neutral kaon particles in 1964, quantum mechanics allows particles to change into their antiparticles and back again in a process known as "mixing". In 2001, The BaBar team, working at the Stanford Linear Accelerator -- and independently the Belle collaboration at the KEK laboratory in Japan -- were the first experiments to detect this in a B meson. BaBar observed "direct" CP violation in 2004 by showing that the number of decays observed for B mesons was higher than for their antiparticle equivalents.

在&间接&过程中，量子力学允许粒子在一种被称为&混合&的过程中，在自身与其反粒子之间相互转变。1964年人们第一次在中性K介子上观测到这种现象。2001年，在斯坦福直线加速器中心工作的BaBar研究组和另一个日本高能加速器研究中心的Belle研究小组各自独立地第一次在实验中观测到这种现象发生在B介子上。2004年，BaBar小组观测到了&直接&电荷宇称不守恒，他们发现观察到的B介子的衰变数量要高于其对应的反物质。

Implications from experimental data for neutral meson mixing and the neutron electric dipole moment are well-studied.

我们也详细研究了关於中性介子的混合与中子的电偶极矩实验数据所衍生的涵义。

Adopting Lorentz-invariant coupling model of neutron-antineutron and neutral meson strong interaction, we have physical analysis and accurate calculation on the neutron and antineutron to two neutral meson renormalization chain diagram propagator, and acquire the theoretical result; furthermore, after application of it to the physical process analysis and cross-section evaluation in this reaction , the differential cross-section of which is given. Moreover, through the comparison among this calculation and those scenarios: neutron-antineutron tree diagram and renormalization chain diagram propagator contribution, some important information about radiative correction was obtained.

采用中子-反中子与中性介子强相互作用的Lorentz不变耦合模型，对中子反中子重整化链图传播子作了有关物理分析及其严格解析计算，获得精确理论计算结果；进而将此结果用于中子反中子反应生成两个中性介子反应的物理过程分析及其截面的计算研究中，并精确计算出中子反中子重整化链图传播下中子反中子反应反应微分截面；最后还将此计算结果与中子反中子树图和重整化单圈链图传播下该反应微分截面作了对比分析，获得了有相关辐射修正的重要信息。

I use an example quoted by Hu Jiaqi:"It is reported that America separates the DNA of a kind of virus by making use of genetic technology and combines it with another kind of DNA. Finally, they get a kind of virulent biological agent called a "pyrotoxin". Someone discloses in private that 20 grams of such a kind of biological agent could result in the global death of 6 billion people due to infection."

我在这里例举胡家奇所引用过的例子："据报道，美国利用转基因技术，将一种病毒的DNA分离出来，与另外一种DNA进行结合，拼结成一种剧毒的"热毒素"生物战剂，且私下有人透露，这种生物战剂只需20克，就可以导致全球60亿人全部感染死亡。"
