what is a kaon zero
&#960+e-&#957e. 1* The neutral Kaons K 0 s and K 0 L represent symmetric and antisymmetric mixtures of the quark combinations down-antistrange and antidown-strange. The charged kaons are mesons which have a quark composition of up-antistrange for the positive kaon and antiup-strange for the negative kaon.ne is called K-zero-short. The other is called K-zero-long. The quark mixing which leads to these combinations involves the exchange of two W bosons. The neutral kaons are important historically for their part in advancing our understanding of quark processes.
