Four giants helps the future
The four giants of physics, ATLAS, CMS, ALICE and LHCb, have started regularly to collect data produced in collisions between accelerated protons, but this time the energy record of 13 trillion electron volts (TeV 13), almost double that which it allowed in 2012 to harness the Higgs boson.
Along the 27 km ring of the Large Hadron Collider (LHC), the superacceleratore CERN in Geneva, the four giants of physics, ATLAS, CMS, ALICE and LHCb, have started to collect data regularly produced in collisions between protons accelerated, but this time the energy record of 13 trillion electron volts (TeV 13), almost double that which allowed in 2012 to harness the Higgs boson.
In the beam pipe, the “magnetic stripe” to 100 meters deep on the border between France and Switzerland, “trains” of packets of protons racing at nearly the speed of light, circulating in opposite directions, driven by powerful superconducting magnets, and clashing at of the experiments.
“It really is with great satisfaction that we see the beginning of RUN2, a new adventure for LHC: the commitment that the Member States of CERN and the international scientific community devoted to the company for decades is now crowned by this new scientific breakthrough and technological LHC, in which Italy plays a major role, “said Fernando Ferroni, president of the INFN. “Scientists are used to working on the borders of knowledge, physicists know it well, especially after putting their hands at the end of a hunt lasted half a century, on the now famous Higgs boson: a discovery that, far from representing a arrival point for modern physics, it is rather a stargate, a true portal to new physics beyond the Standard Model. ”
“This is a new historic day, not only for CERN, but for particle physics in general, and above all is the culmination of the hard work of many people who, during the past two years, has worked hard to improve this machine. ” And ‘what stresses Mirko Pojer, between those responsible for operation of the LHC, for whom “the technological innovation of which LHC is the result allows us to open a new window on fundamental research.”
Physicists are trying to unravel the deepest secrets of matter “splitting it”, in clashes between protons. And, in their push in the infinitely small, they make a leap back in time to more than 13 billion years. Until the early stirrings of the universe, when the universe was formed only by a white-hot, when the Universe was a dense soup of quarks and gluons. The New Physics, making it beyond the Standard Model, the theory that describes today as effectively particles and interactions between them, could be made of space-time dimensions hidden, rolled up on themselves. O of a zoo of supersymmetric particles capable, inter alia, to explain the nature of a quarter of what composes our universe, the so-called dark matter.
“We are at the beginning of a new adventure of knowledge,” say the INFN. “The next expected results from the LHC, in fact, will influence the paths that fundamental research will follow in the years to come.”
