...bubble-chamber picture (see cut), an antiproton from the Bevatron enters at bottom and hits a proton (1): out of the collision come one lambda and one anti-lambda particle. Since both are neutral electrically, they leave no tracks in the liquid hydrogen, but after a short, invisible career, each decays into track-leaving particles by which it can be identified. The lambda ( 2) turns into a proton and a negative pi meson, both of which go off the picture leaving strong curved tracks. The anti-lambda (3) turns into an antiproton and a positive pi meson. The positive...
...lesser but still important finds: a bronze Muse from the era of Praxiteles and a fifth century marble column with the head of Hermes. Archaeologists speculate that an exporter may have warehoused the statues for shipment to Imperial Rome some time during the Augustan Age. and then lost track of them.
