The Large Hadron Collider (LHC) is the world's largest and highest-energy particle accelerator. [1] [2] It was built by the European Organization for Nuclear Research (CERN) between 1998 and 2008 in collaboration with over 10,000 scientists and hundreds of universities and laboratories across more than 100 countries.

A simulated particle collision in the LHC. The safety of high energy particle collisions was a topic of widespread discussion and topical interest during the time when the Relativistic Heavy Ion Collider (RHIC) and later the Large Hadron Collider (LHC)—currently the world's largest and most powerful particle accelerator—were being constructed and commissioned.
This is a list of experiments at CERN's Large Hadron Collider (LHC). The LHC is the most energetic particle collider in the world, and is used to test the accuracy of the Standard Model, and to look for physics beyond the Standard Model such as supersymmetry, extra dimensions, and others.

On 23 November 2009, the first proton–proton collisions occurred at the LHC and were recorded by ATLAS, at a relatively low injection energy of 900 GeV in the center of mass of the collision. Since then, the LHC energy has been increasing: 1.8 TeV at the end of 2009, 7 TeV for the whole of 2010 and 2011, then 8 TeV in 2012.
An intestinal listeria infection tends to cause mild symptoms that are similar to those of other food-borne illnesses, such as diarrhea and vomiting. These symptoms typically start within 24 hours ...
