CDF at Glasgow

CDF at Glasgow

CDF LogoThe Glasgow group has continued to be a driving force in CDF, publishing four Run II analyses in B physics with one of them, a measurement of B cross section, amongst the first of the publications with the Run II and another, the measurement of the B-c mass, being one of the most notable measurements of the Run II programme, obtaining a factor of 100 improvement on the B-c mass determination. Finally, the Glasgow group has established the use of Grid within CDF and turned over a mature global data handling system to the CDF operations group.CDF:

invariant mass[Above] First observation of fully-reconstructed B-c decays and measurement of the B-c  mass ( Glasgow led). Statistical significance of peak exceeds 99.9%. Agreed well with prediction from Glasgow lattice QCD theorists.

The Glasgow CDF group is taking advantage of the high luminosity to measure the high pT physics of Z decays and W pair production with searches for new physics in Z’ and Higgs respectively. We will exploit the window of opportunity to discover the Higgs before LHC begins. We have recognised expertise in the analysis of the W and Z channels: we are driving the key H to WW analysis.

As we improve sensitivity at CDF, we will either exclude the Higgs mass around 160 GeV/c2 or begin to see deviations.   Indications from Standard model fits to the W and top mass plus the LEP fits favour a lower mass Higgs. It is therefore likely that we will exclude the higher mass Higgs before the LHC turns on.  We plan to therefore close the high mass window and then focus on efforts for searches at low mass.

We are also in the ATLAS group and are transferring our knowledge, techniques and programs to ATLAS.  Our experience at the Tevatron certainly indicates that one should not give up too early on searches in difficult channels but apply advanced analysis techniques to eliminate seemingly overwhelming backgrounds.  It is a truly exciting time with a multitude of imaginative analysis strategies and programmes coming together at two accelerators.
