CERN Researchers nearly found Higgs Boson – The God Particle –

40 years ago first time Higgs Boson was theorized by British physicist Peter Higgs and others.
Higgs Boson is sometimes referred as God Particle.



Physicists Peter Higgs, Robert Brout and François Englert suggested that
All particles had no mass just after the Big Bang.
As the Universe cooled and the temperature fell below a critical value, an invisible force field called the ‘Higgs field’ was formed together with the associated ‘Higgs boson’.

The field prevails throughout the cosmos: any particles that interact with it are given a mass via the Higgs boson.

The more they interact, the heavier they become, whereas particles that never interact are left with no mass at all.

Higgs is a particle, or set of particles, that might give others mass.

It will explain why everything in the universe has mass and weight.

The Higgs boson is the signature evidence of the theory - an unstable particle created moments after the big bang before decaying into smaller particles which form the building blocks of the universe.

To find Higgs boson is one of the primary aim of the Large Hadron Collider, a $10-billion particle accelerator operated by the Switzerland-based European Organization for Nuclear Research.

Few think that there is only one Higgs boson and few think that there may be 5 Higgs boson or more.

Last 10 years researchers at CERN's Large Electron Positron Collider (LEP) in Geneva and at Fermilab in Illinois are trying to find the Higgs Boson.

One of the big mysteries that physicists hope to plumb with the Higgs is an idea called supersymmetry.
The Standard Model predicts a wide range of particles, of which the Higgs is the last to be pinned down.
But with supersymmetry, each of the conventional elementary particles in the standard model, including the Higgs, has a companion.

If there's only one Higgs boson, it's part of the Standard Model. But with supersymmetry, there have to be at least five Higgs bosons.

Supersymmetry would double the number of particles to resolve physics problems in a similar way that the prediction--and later discovery--of antimatter did decades ago.

On Tuesday
In a special seminar at the Cern laboratory in Geneva, researchers presented clues in their data which suggest experts may have pinned down the "God particle" at last.

Scientists remained cautious about their findings and insisted they did not represent an official discovery, but admitted the results were "intriguing".

The two teams searching for the Higgs boson at the Large Hadron Collider said they had found hints which point towards a Higgs boson.

The leaders of two experiments, ALTAS and CMS, revealed their findings to a packed seminar at CERN, where they have tried to find traces of the elusive boson by smashing particles together in the Large Hadron Collider at high speed.

"Both experiments have the signals pointing in essentially the same direction," said Oliver Buchmueller, senior physicist on CMS. "It seems that both Atlas and us have found the signals are at the same mass level. That is obviously very important."

Fabiola Gianotti, the scientist in charge of the ATLAS experiment, said ALTAS had narrowed the search to a signal centred at around 126 GeV (Giga electron volts), which would be compatible with the expected strength of a Standard Model Higgs.

"I think it would be extremely kind of the Higgs boson to be here," she told a seminar to discuss the findings. "But it is too early" for final conclusions, she said. "More studies and more data are needed. The next few months will be very exciting...I don't know what the conclusions will be."

We have to wait for next year and may be more years as science when gives answers it puts new challenges before us.
