Large Hadron Collider starts to generate new data – Trade

The largest particle accelerator in the world began with a nearly doubled energy, new phase of unpublished experiments in search of “new physics” that for understanding the mysteries of matter and the world .

At 10:40 local (03:40 GMT-5, Peruvian time), the Large Hadron Collider (LHC, by its acronym in English) provided its first proton collisions at the record energy of 13 TeV (tera), after two years of being subjected to remodeling and repairs.

The LHC, located in a ring-shaped tunnel 27 kilometers in the Franco-Swiss border, began work after the first period of operation, which lasted three years.

In this first stage, the LHC was used to test the existence of the Higgs boson, also known as the God particle, which is supposed to have a key role in the mechanism that causes the mass of elementary particles.

Because of this discovery was awarded the Nobel Prize in Physics in 2013 two of the scientists who had launched the theory of the existence of the Higgs.

“Now we can begin the experience,” said the general director of the European Center for Particle Physics (CERN) Rolf Heuer, but warned not to expect the first results in the coming months.

“The first operation of the LHC (…) that culminated in this exceptional discovery (the Higgs boson) in July 2012 was only the beginning of the trip. Now is the hour of the new physics! The first data begin to arrive. Let’s see what will reveal about the way our universe works, “said Heuer.

According to CERN,” the resumption of data acquisition marks the start of the second season of the LHC, and open unexplored perspectives of physics “territories.

These next few weeks the scientists start recording data collisions at unprecedented energies. Up to 1,000 million collisions occur every second, generating avalanches particle detectors.

In every second of operation of Large Hadron Collider and experiences, several gigabytes of data will arrive at CERN computing center to be stored, selected and shared with physicists around the world

At a depth of 100 meters underground, along the ring Large Hadron Collider , four “experimental”, in charge of scrutinizing detectors collisions then scientists should analyze. p>

Two of these detectors, Atlas and CMS, are versatile and are designed to explore a range of physical phenomena, from the Higgs Boson up dark matter.

Meanwhile, “experience” Alice specializes in plasma ‘quark-gluon’, a state of matter that exists densities or very high temperatures and experts believe that would have existed moments after the Big Bang.

The fourth detector, named LHCb, trying to understand the differences between matter and antimatter, analyzing some quarks (elementary particles).

“We tried to find a gap” theory “standard model”, the theory that integrating current knowledge about particles and fundamental forces, explains Pauline Gagnon, a researcher at CERN.

“It’s a good base, but this model explains only the tip of the iceberg,” he stresses. “It says nothing, for example, about dark matter, unseen because it emits no light, but it represents 27% of the content of the world ” says Gagnon.
