Make way ! The “God” of all particles is here!

Peter Higgs must have been very happy in this week. And the reason is not just elating him, but the entire scientific community is joyous over the momentous discovery at the Large Hadron Collider at CERN at Geneva,Switzerland. The elusive Higgs Boson , popularly called the God Particle has been tentatively confirmed . A particle which is consistent with the Higgs Boson ‘s characteristics has been discovered. The Higgs boson is named after Peter Higgs , who in 1964 wrote one of three ground breaking papers alongside the work of Robert Brout . Francois Englert ,Tom Kibble, C R Hagen and Gerald Guralnik covering what is now known as the Higgs mechanism and described the related Higgs field and boson.
“We have reached a milestone in our understanding of nature,” said Rolf Heuer,the Director general for the European Organisation for Nuclear Research which has been carrying out experiments in search of the Higgs boson at the Large Hadron Collider (LHC), the world’s largest particle accelerator.
“The discovery of a particle consistent with the Higgs boson opens the way to more detailed studies, requiring larger statistics, which will pin down the new particle’s properties, and is likely to shed light on other mysteries of our universe,” Heuer said.
Prof Joe Incandela, spokesman for the CMS, was unequivocal: “The results are preliminary but the five-sigma signal at around 125 GeV we’re seeing is dramatic. This is indeed a new particle,” he told the Geneva meeting
Prof Peter Higgs, after whom the particle is named, wiped a tear from his eye as the teams finished their presentations in the Cern auditorium.
“I would like to add my congratulations to everyone involved in this achievement,” he added later.
“It’s really an incredible thing that it’s happened in my lifetime,” he said.
Famous scientist Prof Stephen Hawking said,”This is an important result and should earn Peter Higgs the Nobel Prize.”
WHAT EXACTLY IT IS :In particle physics,elementary particles and forces give rise to the world around us. Physicists explain the behaviors of these particles and how they interact using the Standard Model—a widely accepted framework believed to explain most of the world we see around us. Initially, when these models were being developed and tested, it seemed that the mathematics behind those models, which were satisfactory in areas already tested, would also forbid elementary particles from having any mass which showed clearly that these initial models were incomplete. In1964 , three groups of scientists,(Peter Higgs Robert Brout . Francois Englert ,Tom Kibble, C R Hagen and Gerald Guralnik), almost simultaneously released papers describing how masses could be given to these particles, using approaches known as symmetry breaking. This approach allowed the particles to obtain a mass, without breaking other parts of particle physics theory that were already believed reasonably correct. This idea became known as the Higgs mechanism (not the same as the boson), and later experiments confirmed that such a mechanism does exist—but they could not show exactly how it happens. The leading and simplest theory for how this effect takes place in nature was that if a particular kind of “field” (known as a Higgs field) happened to permeate space, and if it could interact with fundamental particles in a particular way, then this would give rise to a Higgs mechanism in nature, and would therefore create around us the phenomenon we call “mass”.
WHY THE HYPE ? “Whatever form the Higgs particle takes, our knowledge of the fundamental structure of matter is about to take a major step forward,” the Geneva-based CERN or European Organisation for Nuclear Research press release on Wednesday stated. Professor Soldner-Rembold says:
“Today’s discovery teaches us something fundamental about the building blocks of the universe and how the fundamental particles that build the world around us acquire mass. The Higgs boson matters because it tells us about ‘matter’. This is curiosity driven research and addresses basic questions about the evolution of the universe.
In addition, this curiosity driven research also leads to many important applications. It was exciting to see how today’s seminar at CERN was broadcast via the world wide web to all continents, using the technology pioneered at CERN Particle accelerators have many applications in material science and medicine.
The Higgs discovery pushes the boundary of modern physics and it will
take a while to understand what lies beyond the door we have opened today. No doubt there will be many more exciting discoveries coming out of CERN and the LHC in the next decade.”

THE GOD PARTICLE ? This coinage is debatable. According to wikipedia : The Higgs boson is often referred to as the “God particle” by individuals outside the scientific community, after the title of Leon Lederman ‘s popular science book on particle physics:” If Universe is the answer,what is the question?” While use of this term may have contributed to increased media interest, many scientists dislike it, since it is sensational and overstates the particle’s importance. Its discovery would still leave unanswered questions about the unification of quantum chromodynamics , the electroweak interaction, and gravity, as well as the ultimate origin of the universe. Higgs, an atheist himself, is displeased that the Higgs particle is nicknamed the “God particle”,because the term “might offend people who are religious”.
Lederman said he gave it the nickname “the God particle” because the particle is “so central to the state of physics today, so crucial to our understanding of the structure of matter, yet so elusive,” but jokingly added that a second reason was because “the publisher wouldn’t let us call it the Goddamn Particle, though that might be a more appropriate title, given its villainous nature and the expense it is causing.”
Though the elusive Higgs Boson is believed to be discovered, this in no way is an end to anyresearch its just the beginning of our understanding the infinite universe that is around us.
