Big days for particle physicists
by Zivka Deleva


These days are big for the world of physics. Particle physicists are looking forward to see the results of the particle colliding that should imitate the Big Bang. These are very big days for the particle physicists, said European Organization for Nuclear Research Director General Rolf Heuer. The experiment is made in CERN’s headquarter research center in Geneva. “With these record-shattering collision energies, the Large Hadron Collider experiments are propelled into a vast region to explore, and the hunt begins for dark matter, new forces, new dimensions and the Higgs boson,” said ATLAS collaboration spokesperson, Fabiola Gianotti. “The fact that ! the experiments have published papers already on the basis of last year’s data bodes very well for this first physics run.” Everybody simply waits for the results of the proton collisions, which is going to give new insights into the nature of the strong interaction and the evolution concerning the early Universe. LHC is the world’s largest and highest energy particle accelerator, intended to collide opposing particle beams. Over 2000 graduate students are hardly waiting to see the data from these experiments. Usually, CERN operates its accelerators once an year, they run for seven to eight months, and then shutdown each year. But, now CERN is going to run the Collider for 18-24 months wanting to reach some more data for the experiments to make a significant advances across a wide range of physics channels. “Two years of continuous running is a tall order both for the LHC operators and the experiments, but it will be well worth the effort,” ! said Heuer. “By starting with a long run and concentrati! ng prepa rations for 14 TeV collisions into a single shutdown, we’re increasing the overall running time over the next three years, making up for lost time and giving the experiments the chance to make their mark.”
