Definitions

from The American Heritage® Dictionary of the English Language, 5th Edition.

  • noun Any of a group of four mesons, one positively charged and one negatively charged, having a mass 966 times that of an electron, and two electrically neutral, having a mass 974 times that of an electron. The two charged kaons have the same mean lifetime, about 1.24 × 10−10 second; the two neutral kaons have lifetimes of about 9 × 10−11 second and 5 × 10−8 second.
