21M.2.SL.TZ1.7b
Conservation of energy and conservation of momentum are two examples of conservation laws.
(b)
When a pi meson π- (du̅) and a proton (uud) collide, a possible outcome is a sigma baryon Σ0 (uds) and a kaon meson Κ0 (ds̅).
Apply three conservation laws to show that this interaction is possible.
