As discussed in the section on the trigger, we plan to use two different
running modes. One mode, using only a centrality trigger and lower beam rates and/or
a thinner target, will acquire data on the more abundant low mass systems. These runs
can be done with a target as thin as 4% and beam rates of order per spill or less.
The other mode, using the centrality trigger, a late energy requirement from the
calorimeter, a 20% target and the full beam rate of
per spill, will be used
for high sensitivity searches for high mass systems. In the sections below we will
describe the four main runs planned (one of each trigger type with positive and negative
magnetic field settings) and draw together the rates, acceptance and efficiencies
discussed in other sections to calculate the sensitivities which can be achieved
in each running mode.
The four runs are:
In the sections below we tabulate the systems to be studied in each of these runs. We note that the acceptance of the apparatus is large enough to be sensitive to neutrals in all the proposed runs. Since the metrology and backgrounds are very different for neutrals, the rates and sensitivities will be discussed separately.
