那些更精细的分析并没有发现这种假设的粒子,所以,也许它因为某些原因并不会衰变成底夸克。
Those more-refined analyses have not seen the hypothetical new particle, so for some reason it must not decay into bottom quarks.
在我们的宇宙中,底夸克的质量大约是顶夸克的两倍,造成中子比质子重大约0.1%。
In our universe, the down quark is about twice as heavy as the up quark, resulting in neutrons that are 0.1 percent heavier than protons.
Jaffe和他的同事建立了一个类型的宇宙,其中底夸克比顶夸克轻,而质子比中子重1%。
Jaffe and his colleagues modeled one family of universes in which the down quark was lighter than the up quark, and protons were up to a percent heavier than neutrons.
这些粒子叫做“夸克”,它们有六种不同的“味”,但Jaffe只着眼于最常见的夸克:“顶夸克”、“底夸克”和“奇异夸克”。
These particles are called "quarks" and they come in six different "flavors" but Jaffe only looked at the most common quarks: the 'up,' 'down' and 'strange'.
“过渡物体”包括阿莉萨•安底拉斯克的两个优雅模型,它们是一个名为“介子发射”的设计项目的一部分,这个项目涉及了组成夸克的亚原子粒子介子。
"Transitory Objects" includes two elegant models from Alisa Andrasek that are part of a design project called "Mesonic Emission," a reference to mesons, subatomic particles composed of quarks.
将夸克底的前6项原料混合,然后筛入面粉和烤粉,混合拌匀成团。用保鲜膜包好入冰箱松弛30分钟。
Combine first 6 items for the dough, then sift in the flour and baking powder. Mix until it is completely incorporated. Wrap and chill for 30 minutes.
