In the quark model they are understood to be bound states of a strange quark (or antiquark) and an up or down antiquark (or quark). Kaons have proved to be a … See more The four kaons are : 1. K , negatively charged (containing a strange quark and an up antiquark) has mass 493.677±0.013 MeV and mean lifetime (1.2380±0.0020)×10 s. 2.

Draw a quark level Feynman diagram for the decay K+ → π+π0. This is a weak decay. K+ has strange quark number, N s = −1. The final state has no strange quarks so N s = 0. The number of strange quarks can only change when a W boson is exchanged. 2. Write down all possible decay modes of the W− boson into quarks and leptons.
