Search for anomalous production of diphoton events with missing transverse energy at CDF and limits on gauge-mediated supersymmetry-breaking models
Physical Review D - Particles, Fields, Gravitation and Cosmology 71:3 (2005)
Abstract:
We present the results of a search for anomalous production of diphoton events with large missing transverse energy using the Collider Detector at Fermilab. In 202 pb -1 of pp̄ collisions at √s = 1.96 TeV we observe no candidate events, with an expected standard model background of 0.27 ± 0.07(stat) ± 0.10(syst) events. The results exclude a lightest chargino of mass less than 167 GeV/c 2, and lightest neutralino of mass less than 93 GeV/c 2 at 95% C.L. in a gauge-mediated supersymmetry-breaking model with a light gravitino. © 2005 The American Physical Society.Inside-out tracking at CDF

W boson mass measurement at the Tevatron

Abstract:
The W boson mass (mW) is a key parameter of the standard model (SM), constraining the mass of the unobserved Higgs boson. Using Tevatron pp collision data from 1992-1995, the CDF and DØ collaborations measured mW to δmW = 59 MeV. The ongoing Tevatron Run 2 has produced a factor of 5 more collisions, promising a significant reduction in δmW. CDF has analyzed the first ∼200 pb of Run 2 data and determined its δmW to be 76 MeV.W boson mass and width at the Tevatron
