On 9 April 2014, researchers at the LHCb experiment published a paper validating the existence of an exotic particle, which appears to be a tetraquark. The LHCb spokesperson Pierluigi Campana said: “We are very happy to have confirmed this particle, which is in fact a very strange object.”

Precisely 50 years ago, George Zweig and Murray Gell-Mann independently introduced the Quark Model, which is a fundamental cornerstone in particle physics. The model is a perfect tool to understand how matter interacts…

LHC delivers collisions at record energy

By Gianluigi Arduini. Published on 19 April 2012 in:
News, , , , , , ,

After a three-month winter maintenance stop, the Large Hadron Collider [LHC] at CERN has resumed operation, with beams, on 14 March. Two days later, low intensity beams were accelerated to 4 TeV for the first time, achieving a new world record.

During the preceding month, all machine components – including almost 2,000 superconducting magnet circuits – were tested for operation at currents which allow these accelerating beams of up to 4 TeV…
