This sketch shows the proper assignments of a particle to each track, corresponding to the third observation of the production of a negatively-charged Omega meson in a hydrogen bubble chamber photograph. The paths of neutral particles, which produce no bubbles in the liquid hydrogen and therefore leaves no tracks, are shown by dashed lines. The presence and properties of the neutral particles are established by the analysis of the tracks of their charged decay products or the application of the laws of conservation of mass and energy, or a combination of both. The incoming K-negative meson from the Alternating Gradient Synchotron collides with an unseen, stationary proton in the liquid hydrogen with the resultant production of a neutral K-meson, and.
