Two different decays were found for charged strange mesons: Θ → π + π τ → π + π + π The intrinsic parity of a pion is P = −1, and parity is a multiplicative quantum number. Therefore, the two final states have different parity (P = +1 and P = −1, respectively). It was thought that the initial states should also … See more In particle physics, a kaon , also called a K meson and denoted K , is any of a group of four mesons distinguished by a quantum number called strangeness.
