LHCb in the hunt of tetraquarks

In 2003, the Belle collaboration reported the observation of an unexpected new particle, showing up in the mass spectrum of J/ψ π π candidated. Its mass was somewhat close to the value expected for the yet unobserved χc1(2P) charmonium, but its…

CERN experiments find first evidence for rare Higgs boson decay

The strength of the interaction between the Higgs field and a particle determines the mass it obtains from the Higgs and it is a mystery why the interaction strength is different for different particles. This puzzle is exacerbated as the leptons,…

ATLAS presents a strategy for a general search of new physics

One of the main goals of the Large Hadron Collider is to look for signals beyond the Standard Model (the other major goal has already been fulfilled with the discovery of the Higgs boson). To this day scientists are still lacking clues. Could it be…
