"Seen for the first time the transformation of neutrinos. "
May 31
For the first time in the world and 'observed the''metamorphosis''of a neutrino : one of the particles' small and elusive so far Notes can change identity, 'transformed from one type of neutrino into another type of neutrino. The result' was achieved in Italy, Gran Sasso National Laboratory of the National Institute of Nuclear Physics (INFN). This discovery, pursued years by physicists around the world, opens the doors to opportunity 'to comply with other physical phenomena never seen before. The result is' only a first taste of''physics''of the future and now must' be confirmed by further observations. The first''''of neutrino oscillation and 'was observed at the end of the journey of trillions of neutrinos that three years ago were''fired''from CERN in Geneva to the Gran Sasso Laboratories. The particles have passed through the rock at the speed 'of light, covering the distance in 2.4 milliseconds to 730 kilometers separating the two research centers in the draft Cngs (CERN Neutrino to Gran Sasso). Watch the transformation and 'was like finding a needle in a haystack (was due in a few cases out of billions of particles). To see it, and 'Opera was the experiment (which Italy participates in international cooperation), a type of muon neutrino and we 'turned in another of the three families of neutrinos so far known, the type tau. The metamorphosis observed confirms that one of the boys away Panisperna, Bruno Pontecorvo, predicted more than half a century ago and, most importantly, confirmation that neutrinos have mass. A statement, this one, which contradicts the theory considered the benchmark of contemporary physics, the so-called Standard Model, which states that neutrinos have no mass. "Discovery Cern, maybe it matters big bang"
September 21: The particle accelerator more 'big world keeps its promises to even six months from the initial collision, the Large Hadron Collider (LHC) at CERN in Geneva has produced something never seen before'',''as physicists have said. L 'hypotheses' fascinating and charming and' having been produced something very similar to the primordial matter appearance in the universe a few microseconds after the Big Bang. The data (including the option of the primordial plasma) were presented today at a seminar at CERN.
