TeV stands for terra electron volt. We have encountered these type of names earlier. Like a calorie TeV is also a unit of energy useful in modern particle physics. So how much is a TeV of energy? Filip Tanedo says:
A TeV is roughly the kinetic energy of a flying mosquito.He quotes this page. Now since these energies are relevant for the Large Hadron Collider at CERN, Geneva and the Physics Department of AMU has a group participating in LHC experiments therefore it is nice place to get linked with what is happening in that exotic field. Tanedo has tried the impossible-to explain the title, and the content, of a oven hot paper from Tevatron at another particle physics laboratory called the Fermilab in USA.
