Higgsov bozon

Jedna moguća signatura Higsovog bozona iz simuliranog proton–proton sudara. Raspada se skoro trenutno u dva mlaza hadrona i dva elektrona, vidljivih kao linije.

Higgsov bozon je hipotetska elementarna čestica kojom se prema Standardnom modelu objašnjava masa drugih čestica, a posebno zašto su W i Z bozoni masivni za razliku od fotona koji nemaju masu.

Teoriju postojanje takvog bozona postavio je 1964. godine škotski fizičar Peter Ware Higgs.

Higgsov bozon do danas nije eksperimentalno dokazan. Predviđa se da će biti dokazan pomoću velikog hadronskog akceleratora (engleski Large Hadron Collider ili LHC) koji se dovršava u CERN-u (Evropskom centru za nuklearna istraživanja) nedaleko od Ženeve (Švicarska). Dokazivati će se sudarima proton-proton za koje se tvrdi da bi mogli dovesti do nastanka Higgsovog bozona.
