Scientists at the Department of Energy's Fermi National Accelerator Laboratory
announced on June 9, 2004 new results that change the best estimate of the mass
of the postulated Higgs boson from approximately 96 GeV/c2 to 117 GeV/c2.
Compared to the previous value, the
new value is in better agreement with direct searches - such as those conducted
by CERN experiments - that excluded a mass below 114 GeV/c2. In a
paper to appear
in the June 10 issue of Nature magazine, physicists of Fermilab's DZero experiment
report on results obtained by applying a new analysis technique to data obtained
from 1992 to 1996 during Collider Run I at the Fermilab Tevatron, the world's
highest-energy particle accelerator.
