具质量粒子
(重定向自慢子)
具质量粒子(massive particle)是指其静止质量为非零实数的粒子。依照狭义相对论,这些粒子的速度都会比光速要慢[1],像质子、中子、电子都是具质量粒子。基本粒子中的夸克都是具质量粒子,玻色子中的W玻色子、Z玻色子和希格斯玻色子也是具质量粒子。
暗物质
编辑具质量粒子的分类中。包括了假想存在的大质量弱相互作用粒子及稳定具质量粒子,目前假想暗物质是由这些粒子所组成[4] 。

Just as ordinary particles ('tardyons') can never be accelerated to the speed of light, so tachyons can never be slowed down to the speed of light.
