Consider K meson of mass mK decaying into two pions of mass each, in the laboratory frame. Show that the energy of each pion is equal to
and the momenta are
.
Consider a K meson at rest in the laboratory frame, decaying into two identical pions, each of mass (m_\pi). By conservation of energy and momentum, the total energy and momentum before and after the decay must be equal.
