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+).
