The European Laboratory for Particle Physics ( CERN ) announced that it has reached a new record of energy in new tests carried out in order to advance to study how was the state of matter just after the Big Bang, the event that would have formed the universe.
The energy fu e about twice that of any previous experiment, reaching temperatures of billions of degrees (hundreds of thousands of times inside the Sun), a week after starting the first collisions of lead ions, said CERN .
This marks the beginning of a month loaded collisions of lead ions (lead atoms without electrons).
The collision ion is a “tradition” that the CERN makes for one month a year. But this time “will be special, because we have reached a new energy and explore the matter in an even earlier period of our universe,” said in a statement the director general of the institution, Rolf Heuer.
the early universe, a few millionths of a second, the matter was a very hot and dense medium, a kind of ‘primordial soup’ made up of elementary particles, known as “quarks” and “gluons”. The latter hold the quarks together inside protons and neutrons that make up matter.
During the first period of operation of the Large Hadron Collider (LHC), between 2010 and 2013, there were significant advances in the understanding of the properties of plasma of quarks and gluons.
Now “jump Energy gives us access to more fundamental questions such as the precise mechanisms of production of this state of matter, “said the researcher from the University of Santiago de Compostela, Carlos Salgado.
The ATLAS experiment spokesperson, one of the four particle detectors LHC-, Dave Charlton, explained that these experiments “will provide a great complement to the proton data” collected so far
