Abstract:
A direct measurement of the W boson total decay width is presented in proton- antiproton collisions at y/s = 1.96 TeV using data collected by the CDF II detector. The measurement is made by fitting a simulated signal to the tail of the transverse mass distribution in the electron and muon decay channels. An integrated luminosity of 350 pb_1 is used, collected between February 2002 and August 2004. Combining the results from the separate decay channels gives the decay width as 2.038 0.072 GeV in agreement with the theoretical prediction of 2.093 0.002 GeV. A system is presented for the management of detector calibrations using a relational database schema. A description of the implementation and monitoring of a procedure to provide general users with a simple interface to the complete set of calibrations is also given.
