• 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.

    我们宇宙中,底夸克的质量大约顶夸克的倍,造成中子质子重大约0.1%。

  • When you go below atomic size and get down to quarks, you drop off the periodic table and start playing with James Joyce who coined the word "quark."

    原子那么想到夸克,放下元素周期表跟发明了“夸克”这个词的詹姆斯乔伊斯一起玩儿

  • 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.

    Jaffe同事建立一个类型的宇宙其中夸克顶夸克质子中子1%。

  • The phenomenological constraints on the down-quark mass matrix in the weak interaction base were investigated.

    夸克相互作用下,得到了下夸克质量矩阵唯象约束条件
