The Large Hadron Collider will be upgraded to search for dark matter

No sooner had the scientists working with the most expensive scientific experiment in the world, discover the Higgs boson, as immediately moved svoiego focus attention on the resolution of another exciting task: the mysterious dark matter.

The Large Hadron Collider of CERN laboratory, near Geneva, will be updated by the end of this decade, at a cost of $ 2.8 billion and will find answers to the great mysteries of the universe.

Physicists believe that it is the dark matter of the universe does not fly apart. It accounts for 84 percent of all matter, and in spite of that, it has not been able to see, because it does not create and does not reflect light.

Scientists hope that the 10-fold increase in energy particle beams colliding with each other within a 27-kilometer-long tunnel will create and detect dark matter. These plans have already been approved by the governing board of CERN. For modernization, this particle accelerator, the construction of which cost $ 6.6 billion, will be shut down for at least two years.

This decision was taken after the physicists at CERN announcement of the opening of the particle, which resembles the elusive Higgs boson, and plays a key role in giving the mass of the particles.

But there is still a lot of research to work with the Higgs boson. Many observers, both from CERN, and outside it, have expressed concern that people may find work with an open boson is fully implemented. Other experiments will be carried out before the end of the year, after which the android Collider shut down for 20 months for repairs.

Collider collide with each other protons - particles in the nucleus of all atoms, which leads to a temperature of about 4 trillion degrees Celsius. It’s 250,000 times hotter than the center of the Sun.

Detectors identify fragments that occur after the collision. Scientists hope that upgrading to 2020 will allow them to find some of the most rare particles.

Lead Coordinator upgrade detector ATLAS, Phil Allport of the University of Liverpool, said: "In essence, we will seek major distortions in those particles that will emerge after the collision. Simply put, if the energy is very high and the particles go to the left, not the right, the so there you need to look dark matter. "
