FIGURE 14.7
Two-jet event. Two tightly collimated groups of reconstructed charged tracks
can be seen in the cylindrical central detector of UA1, associated with two
large clusters of calorimeter energy depositions. Figure reprinted with permission from S Geer in High Energy Physics 1985, Proc. Yale Advanced Study

FIGURE 14.8
Four transverse energy distributions for events with
E T > 100 GeV, in
the θ, φ plane (UA2, DiLella 1985). Each bin represents a cell of the UA2
calorimeter. Note that the sum of the φ’s equals 180
0 (mod 360
0 ).
