ALICE with a side order of muons
The lead ion program continues. ALICE is giving us a window to the first moments of the universe by better understanding plasmas. The beam is horizontal in this side view. The tracks on the right, the detector's main section, show particles from the hot dense plasma created in the heavy ion collision. The curving tracks going to the the left are muons created in the same interaction.
