Tevatron Announces Higgs Finding Ahead Of CERN’s July 4 Announcement

Just two days before the highly anticipated announcement of the latest Higgs-search results come out from the Large Hadron Collider in Europe, the U.S. Department of Energy´s Tevatron collider scientists failed to announce a finding first, but did present more evidence.
“The Tevatron experiments accomplished the goals that we had set with this data sample,” Fermilab´s Rob Roser, co-spokesperson for the CDF experiment at DOE´s Fermi National Accelerator Laboratory, said in a press release. “Our data strongly point toward the existence of the Higgs boson, but it will take results from the experiments at the Large Hadron Collider in Europe to establish a discovery.”
The Large Hadron Collider (LHC) results will be announced at a scientific seminar Wednesday, July 4, at the CERN particle physics laboratory in Geneva, Switzerland.
The scientists at CERN were expected to announce they had found the Higgs-Boson particle, or God particle, back in December 2011, but left a few onlookers disappointed as they had only announced "promising signs."
However, the European scientists will be back at it in a couple of days to unveil its developments in the hunt for the God particle.
“It is a real cliffhanger,” DZero co-spokesperson Gregorio Bernardi, physicist at the Laboratory of Nuclear and High Energy Physics, said in a press release. “We know exactly what signal we are looking for in our data, and we see strong indications of the production and decay of Higgs bosons in a crucial decay mode with a pair of bottom quarks, which is difficult to observe at the LHC.”
The Tevatron results are months behind what the CERN scientists have found, unveiling the same evidence that LHC showed teams last year.
The U.S. scientists said the Higgs particle has a mass between 115 and 135 gigaelectron volts, which is a similar, but broader, range than what CERN scientists announced in December last year. The CERN team said the elusive particle lies between 115 and 127 GeV.
The particle would either help confirm or complicate the understanding of the universe by potentially explaining, or muddying up, how the stars and planets formed after the Big Bang.
While most scientists believe the particle exists, it has still not been confirmed yet, and institutions have both collaborated, and raced to try and find a way to do so.
"During its life, the Tevatron must have produced thousands of Higgs particles, if they actually exist, and it's up to us to try to find them in the data we have collected,” Luciano Ristori, co-spokesperson of the CDF experiment and physicist at Fermilab, said in the release. “We have developed sophisticated simulation and analysis programs to identify Higgs-like patterns."
Ristori said it would be easier for someone to look for their friend's face in a sports stadium filled with 100,000 fans than to search for a Higgs-like event.
Either all doubts will be put to rest, or the hunt will just continue on after the main event by CERN on Wednesday.
