Homework Help: Quark composition of Neutral Antikaon?

  1. May 11, 2008 #1
    I need to determine the quark composition of the neutral antikaon. Below is a copy of my multiple choice question.

    Here is my attempt at a solution:

    First, a neutral antikaon is a meson. This means it must be composed of a quark-antiquark pair. A neutral antikaon has charge of 0 and strangeness of -1. From the six known quarks, the composition must be a strange quark and an antidown quark.

    I tried selecting [tex]s \bar{d}[/tex] but that is incorrect. How?

    For a table of needed quark properties, see http://hyperphysics.phy-astr.gsu.edu/hbase/Particles/quark.html" [Broken]
