The D0 experiment runs at the Fermilab Tevatron Collider located near
Chicago, IL. The Tevatron accelerator provides proton, anti-proton
collisions at an energy of 2 TeV. The first data taking period was from
1992 to 1996, and a second data taking period began in 2001 and is still
continuing.

Stony Brook was one of the founding institutions of D0. We have built
major pieces of the apparatus and carried out research in almost all
areas in which D0 has published results from QCD, through B physics, top
quark and W boson measurements and searches for hypothetical new
particles.

Measuring consistency between Standard model predictions and results from
experiments can be used to set limits on Higgs boson mass. The limiting
factor in this constraint is the precision of the measured W boson mass.
Stony Brook plays a major role in this work. A recent paper by DØ
Phys. Rev. Lett. 103, 141801 (2009) is the world’s most
precise W boson mass measurement and is shown below.
