Why do we need the Large Hadron Collider?
This year, scientists expect to reproduce in the nuclear laboratory those early pristine conditions, when there were no protons and neutrons, and was a solid quark-gluon plasma. In other words, the researchers hope to see the world of elementary particles, as it was a mere through share microseconds after the Big Bang, that is, after the formation of the Universe. The program is called “How it all began”. In addition, for more than 30 years in the scientific world lined up theories explaining the origin of the mass of elementary particles. One of them implies the existence of the Higgs boson. This elementary particle called the divine. As said one of the CERN staff, “catching the traces of a Higgs boson, I will come to their grandmother and say: look, please because of that little thing, you have so many extra pounds”. But experimentally the existence of the boson is not yet confirmed: all hopes on the LHC accelerator.
Large hadron Collider a particle accelerator, thanks to which physics will be able to penetrate so deeply into matter than ever before. The essence of the work at the Collider is to study the collision of two beams of protons with a total energy of 14 TeV is on one proton. This energy is millions of times greater than the energy released in the individual act of thermonuclear synthesis. In addition, experiments will be run with the lead nuclei colliding at an energy of 1150 TeV.
The LHC will provide a new step in a series of discoveries of particles that began a century ago. Then the scientists have only just discovered all kinds of mysterious rays: x-rays, cathode rays. Where they occur the same whether the nature of their origin and, if Yes, what is it?
Today we have answers to questions, allowing a much better understanding of the origin of the Universe. However, at the beginning of the XXI century we are facing new questions, the answers to which scientists hope to obtain with the help of the accelerator tank. And who knows what new areas of human knowledge will entail the studies. In the meantime, our knowledge of the Universe is insufficient.
Says corresponding member of RAS Institute of high energy physics:
Collider involved a lot of physicists, which connect certain hopes with discoveries that can occur there. The main event which can happen is the discovery of the so-called hypothetical Higgs particles Peter Higgs eminent Scottish physicist. The role of this particle is extremely important. She is responsible for the education of the mass of other elementary particles. If a particle does, then it will be the greatest discovery. It would confirm the so-called Standard model, which is now widely used to describe all processes in the microcosm. While this particle will not be opened, this model cannot be considered fully justified and confirmed. This, of course, the first thing to what scientists expect from this Collider (LHC).
Although, generally speaking, nobody believes that the Standard model is the ultimate truth. And, most likely, according to most theorists, it is an approximation or, some say, a “low energy approximation” to a more General theory which describes the world at distances a million times smaller than the size of the nuclei. It’s like Newton’s theory is a “low energy approximation” to the Einstein theory of relativity. The second major challenge with the LHC is to try to go beyond this Standard model, that is, to make the transition to the new space-time intervals.
Physics will be able to understand in which direction we must move to build a more beautiful and a more General theory of physics is equivalent to small space-time intervals. The processes taught there, they reproduce in fact the formation of the Universe, as saying, “the Big Bang”. Of course, this is for those who believe in this theory that the universe was created this way: an explosion, then the processes at super high energies. Stipulated time travel may be associated with the Big Bang.
Anyway, tank is a pretty serious promotion in the depths of the microcosm. So can open completely unexpected things. I will say one thing that the Tank can be opened absolutely new properties of space and time. In which direction they will open now hard to say. The main thing to break further and further.
European organization for nuclear research (CERN) is the world’s largest research center in particle physics. To date, the number of participating countries increased to 20. About 7000 scientists from 500 research centers and universities, use of experimental equipment at CERN. By the way, in the work on the Large hadron Collider took part and Institute of nuclear physics. Our specialists are now busy assembling and testing equipment, which is developed and manufactured for this accelerator. It is expected that the Large hadron Collider will be launched in May 2008. As expressed by Lin Evans, the head of the project, the accelerator lacks only one part a big red button.
