TOF Multiplicity and TOF tracks.
¥The TOF multiplicity is
strongly correlated with the centrality of the collision.
¥For B = 0 data, we have
shown the measured multiplicity, after correcting for the secondary ratio, is
consistent with the charged-particle yields extracted from the silicon
data. The ratio of primaries to
secondaries is 0.45.
¥For field-on data, the
number of secondaries is reduced and the ratio of primaries to secondaries is
0.53 (B-) and 0.59 (B+).
