The Higgs boson, the particle that contains the mystery of the origin of the universe and physicists pursued, might not be as unique as
believed
After all, the Higgs boson , "the God particle" which contains the mystery of the universe's mass, that physicists look for years and is expected to be finally revealed by the large particle accelerator LHC , may not be as "unique" as previously thought. In fact, the only logical explanation for the latest experiment at the Tevatron, the particle accelerator at Fermilab North American in Chicago, is that there are five, not one, kinds of different Higgs boson
In The experiment, conducted by the DZero group the Tevatron , were colliding protons and antiprotons. And the results showed that the collisions had risen a great deal more matter than antimatter. Which, moreover, it seems logical, and also consistent with what happened during the Big Bang , 13,700 million years ago, when our universe came into existence.
However, the "advantage" of matter over antimatter detected by the DZero group during the experiment is much higher than it is supposed to happen during the Big Bang. That forces us to consider whether there are any "new physics" to be discovered.
If during the Big Bang, when our whole world was nothing but a soup of particles colliding with each other crazy because of the extremely high temperatures had maintained the balance and these crashes have raised the same amount of matter than antimatter, our universe simply does not exist, because matter and antimatter, to come together, they cancel each other. Fortunately, our very existence shows that during the Big Bang there was an imbalance in favor of matter. Unfortunately, the physics that attempts to ascertain the reasons for this "bias" is meaningless.
"Hunt the Higgs"
Physicists then began to wonder if the model standard, that classifies and assigns a specific function and each of the particles exist, they hide some kind of "surprise" yet undiscovered. Now if that is so. How should this "new physics"? Researchers at the Tevatron with your experiment, think they have found a solution. One that points to the disturbing possibility that there are five different types of Higgs boson, all with the same mass, electric charge three with no one, another positively charged and the last type, negatively charged.
researchers themselves explain their idea: "in models with more than one type of boson Higgs easy to explain the effects observed in our experiment. What is complicated is that these effects occur without affecting anything other than what is being measured. "Or what is, how difficult is to explain the matter-antimatter asymmetry without the rest of the Standard Model to collapse.
Research can provide clues and suggest new methods to hunt once a Higgs and complete the Standard Model. Even if you have to make room for five new partners instead of just one.
