2.5 Synopsis
We are working on three major hardware upgrade projects:
COT: The COT replaces the CTC which would be inadequate for the higher luminosities
of Run II. We are building much of the actual chamber and are responsible for
testing and calibrating it. We will soon begin working on the new online and oine
software required for this new device.
SVX: The new SVX will be much longer and will provide 3D tracking. We have
designed and fully debugged the readout controller (SRC) and are now writing and
debugging much of the software required for data acquisition.
CMX: The CMX coverage was incomplete in the last run. To complete it, we are
installing chambers where the Main Ring used to pass over the detector, and in the
lower 90 in azimuth beneath the nominal oor. We are involved in rewriting the oine
code and will become involved in the online soon.
Our recent successes in the analysis of Run I data include two very important measurements
and apowerful search for Supersymmetry:
top cross section: A new and much improved measurement of pp ! tt has been
approved for publication by the collaboration.
W mass: We have completed the nal measurement of the W mass in the electron
channel, which will be published together with the muon channel this summer.
6E T + jets: Our control of the 6E T measurement has greatly increased the sensitivity
of this channel to physics beyond the Standard Model. A result is expected soon.
We are shifting much of our analysis eorts toward Run II. Some of current plans and
activities include:
di-boson production: The W +Jets and 6E T +Jets samples will contain contributions
from WW and WZ production. They may also be windows to New Physics, including
the Higgs boson.
monojets: We will apply our expertise in 6E T measurement to a monojet search. A
null result would constrain theories of electroweak-gravity unication via large extra
dimensions.
