Science DiscussionsAccording to the March 13, 2009 Fermilab press release “Fermilab experiments constrain Higgs mass,” the CDF and DZero collider experiments earlier predict that “… the Higgs particle should have a mass between 114 and 185 GeV/c2,” where GeV stands for gigaelectron volts and c2 represents the square of the speed of light. However, the analysis of the latest experiments (using CDF and DZero) performed on the Fermilab’s Tevatron collider, reduces that mass range to a much lower amount. The Fermilab report states, “Now the CDF and DZero results carve out a section in the middle of this range and establish that it cannot have a mass in between 160 and 170 GeV/c2.” The scientists at Fermilab (formally called the Fermi National Accelerator Laboratory) used two separate experiments, from CDF and DZero, and then combined them together so they could analyze the combined data. This burst of new information helped them reach their new conclusion of the smaller mass range of the Higgs boson, which is sometimes called “The God Particle.” According to the Fermi article, “CDF is an international experiment of 602 physicists from 63 institutions in 15 countries. And, “DZero is an international experiment conducted by 550 physicists from 90 institutions in 18 countries.” CDF stands for Collider Detector at Fermilab, while DZero is another name for the DØ Experiment.
