The Fermilab is approaching the Higgs boson particle detection

The Fermilab is approaching the Higgs boson


Laboratory Scientists Fermi National Accelerator in Illinois, home of the Tevatron particle accelerator, say their old machine is now at least a 50% chance of observing the elusive Higgs boson end of next year.

The estimate is based on the efficiency of the accelerator to produce collisions of high energy particles
taking place now the most general and
chance that the Higgs mass falls within a range detectable by Fermilab

Hadron (LHC) at CERN and its more than six months of waiting until it is restarted,
and another year or more before publishing the data, it appears increasingly likely that the Tevatron will
clear track to be the first to observe the Higgs.

"We're not in a race against CERN," says the director of Fermilab, Pier Oddone, who notes that many other Physicists working at the Tevatron are also heavily involved in the LHC. However, other Fermilab scientists told New Scientist that the sense of competition is real, and that investigators are "working like mules" by analyzing data from two key experiments Tevatron particle, known as CDF and DZero.

"Indirectly, we are helping them," said DZero spokesman Dmitri Denisov of their European counterparts. "I definitely feel the heat and work a little harder."

previous experiments and theoretical models predict that the Higgs boson, which is widely believed to be the last undiscovered particle in the so-called Standard Model of particle physics has a mass that is equivalent to between 114 and 184 GeV (billion electron volts). This range falls within the sensitivity of the Tevatron, which suggests that if the Higgs is real, just a matter of time appears at Fermilab.

increasingly likely


Picture of the 2 rings: the main injector (front) and the Tevatron ring (background). The circular pond around them help dissipate the heat produced by the facility.

But that window may exist in which Higgs is shrinking, in a way that favors the Tevatron.

Data published last summer by both CDF and DZero excluded a value of 170 GeV, where the Higgs boson highlight particularly well against the background noise of other interactions of particles. Data collected since then continue to expand the possibilities of detecting both sides of that value.

That means that the closer the mass of the Higgs of 170 GeV, the greater the chances that looks at Fermilab. Denisov

estimates that may arise evidence for a Higgs boson of 150 GeV as soon as this summer, well before the LHC is planning even his start after his injury last year. Alternatively, if the Higgs mass is 120 GeV, would likely see before the end of 2010 according to scientists at the Tevatron trust.


clear signal


One thing that will help physicists is the fact that the Tevatron collides protons with anti-protons. The resulting collisions create less background noise than the proton-proton collisions are expected to occur in the LHC.

"We could not be in a better position," say Jacobo Konigsberg, a physicist at the University of Florida in Gainesville, which is co-spokesperson for CDF experiment. "The Tevatron is running beautifully and in the next two years could double the data obtained during the last eight." Source

On November, 2007 the most complex scientific instrument ever built will be switched on. The Large Hadron Collider promises to recreate the conditions in the early universe. By revisiting the beginning of time, scientists hope to unravel some of the deepest secrets of our Universe.

Within these first few moments the building blocks of the Universe were formed. The search for these fundamental particles has occupied scientists for decades but there remains one particle that has stubbornly refused to appear in any
experiment. The Higgs Boson is so crucial to our understanding of the Universe that it has Been dubbed the God particle. Explains how fundamental it Particles acquire mass, or as one scientist Plainly states: "It is What Makes stuff
