New Particle Discovered?

Researchers at Fermilab recently discovered a particle that had never previously encountered.

Although this particle is not a Higgs boson, which has been sought by physicists, but these findings are suspected to be a new proof of the existence of new particles in nature.

As reported by MSNBC, researchers discovered these particles through atomic-breaking tool in the physics laboratory Fermilab Tevatron, in Batavia, Illinois, United States.

When they threw the electrons and antiprotons through the rings along the 4 miles at speeds approaching the speed of light, it formed a massive energy beam of particles with up to 144 giga electron volts (GeV).

So far there are no  particles  that have energy for it. Higgs boson particle, which is believed to be  the most elementary particles of a body, and gives mass to other particles, is predicted to only have 115 to 185 GeV energy.

But the pattern of these particles is not similar to Higgs Boson particle characteristics agreed upon by experts. "If this really is a new particle, this can not be explained by model standards," said Pierluigi Catastini, one of the researchers who carried out this invention.

Therefore, Catastini said, they need a new model to explain the pattern of this new particle.

"The whole world of physics was surprised with this result," said David Kawall, from the University of Massachusetts Amherst, as quoted by the website LiveScience. The same is said by Michael S. Turner, Director of the Kavli Institute for Cosmological Physics at the University of Chicago.

According to Turner, this invention is a great discovery. "This is an unexpected discovery that could alter the high energy physics and cosmology," said Turner.

However, not all researchers agree. Sheldon Stone, a researcher from Syracuse University, said that the discovery was still not enough to have the data. "I do not believe it. The discovery is very dependent on the detailed background of the experiment, and small changes can change all these results," he said.

However, the statistical significance of experimental data has exceeded three standard deviations. This means the possibility of this discovery is just a random anomaly, which is smaller than a thousandth. Therefore, the present invention can be practically significant, although not yet be dikonklusikan.

If further measurements are to be determined, and the pattern has met five standard deviations, of course, many more physicists who recognize the present invention.
