April 29, 2012 - An entirely new kind of particle has been discovered by scientists making use of the world’s largest and most strong particle accelerator, the Large Hadron Collider (LHC), near Geneva, Switzerland.

The discovery of the new particle, referred to as “neutral Xi_b^star baryon,” was made by the CMS experiment, one of 6 separate particle physics experiments operating at the LHC. It was announced Friday by Symmetry Magazine.

“Besides helping to fully grasp how quarks bind and therefore further validate the theory of strong interactions, one of the four standard forces of physics, this measurement represents a tour-de-force that opens up great perspectives for long term discoveries,” wrote Carlos Lourenco, a senior researcher with the European Organization for Nuclear Research (CERN), the organization that oversees the experiments at the giant accelerator, in an e mail to TPM.

The new type of particle is so unusual that it can't arise anywhere else on Earth outside of the accelerator, and only sometimes in outer space.

“It might get made once in a whilst, when a substantial-energy cosmic ray collides with the moon, for instance,” Lourenco told TPM.

The particle’s rarity is due in portion to its composition: It is made up of three quarks which commonly are not located locked together.

“When these three quarks get with each other, they instantly divorce, instantaneously,” Lourenco explained.

The new particle was truly created in 2011, when the CMS researchers collected collisions between two beams of protons going in opposite instructions through the 17-mile-long underground ring that comprises the LHC accelerator.

When the two beams smash into one another, they create countless debris, a reaction developed to simulate the situations just after the “big bang,” the theorized occasion that birthed the Universe, hence the LHC’s nickname as the “big bang machine.”

But the debris, which may possibly contain previously unknown times of particles, are incredibly tiny, and only last for an unfathomably quick time just before decaying into nothing at all.
 
In truth, in the situation of the new particle, by neutral Xi_b^star baryon, the existence of the particle itself was so brief that it could not be detected right, but rather by its decay signature.

“We managed to find it nevertheless,” Lourenco stated. “It is a ‘strongly decaying resonance’. It lives for much less time than you or me can picture.”

“However, the Xi_b^star breaks up in a recognized cascade of decay items,” Lourenco continued. “Ernest Aguiló, a postdoc from the University of Zurich, identified traces of the respective decay merchandise in the information and was able to reconstruct the decay cascades commencing from the Xi_b^star decays.”

A diagram of the decaying process of neutral Xi_b^star baryon can be witnessed beneath. The black star signifies the initial collision, with the arrows representing the decaying quarks that make up the particle.

As for why it took the CMS researchers a number of months to reveal their groundbreaking particle physics find to the planet, he said: “It will take a while to verify every little thing in detail and convince our colleagues and ourselves that this is a genuine particle and not a statistical fluctuation or some other spurious impact.”

To be clear, neutral Xi_b^star baryon is not the very same thing as the long-sought Higgs boson, the famed “god particle” that is responsible for providing anything in the universe mass, which scientists are hoping that the LHC will be able to discover later on this year.

“The Higgs mechanism, despite its fame, is responsible for only .1% of the matter in the Universe,” Lourenco told TPM.

Now, nevertheless, there is celebrating to be completed by the CMS researchers.

“It also justifies opening a bottle of champagne, if you need a justification for that,” Lourenco stated, of the discovery of the neutral Xi_b^star baryon.

Editor’s note: This article was up to date to incorporate far more thorough data about the discovery of Xi_b^star baryon.
