ALICE 13 TEV PROTON COLLISIONS, CERN GRAPHIC

ALICE 13 TeV proton collisions. Graphic of the first test collisions of protons at an energy of 13 TeV, as recorded by the ALICE at CERN on 20 May 2015. ALICE (A Large Ion Collider Experiment) is a detector built around the Large Hadron Collider (LHC) at CERN (the European particle physics laboratory) near Geneva, Switzerland. The LHC, the world's largest and most powerful particle collider, began operating in 2008. For ALICE, beams of ions are accelerated to collide head-on. The collision energy creates new particles that will decay into other particles. These will be detected by the many detector layers around the central collision point. The LHC energies have allowed study of exotic material like quark-gluon plasma, a form of quark matter.(KEYSTONE/SCIENCE PHOTO LIBRARY SPL/CERN, the ALICE Collaboration/SCIENCE PHOTO LIBRARY)

SCHWEIZ CERN PETER HIGGS

Peter Higgs( b.1929), British theoretical physicist. In 1964, Higgs predicted the existence of a new type of fundamental particle, called the Higgs boson, that is thought to give other particles mass. This particle is required by many of the Grand Unified Theories (or GUTs) which hope to explain three of the fundamental forces (electromagnetism and the weak and the strong nuclear forces) in a single unified theory. The Higgs boson is yet to be detected experimentally, but it is one of the main challenges of high-energy particle accelerators such as the large hadron collider (LHC) at CERN (the European particle physics laboratory).
