Higgs mechanism
Proposed in 1962 by Philip Warren Anderson
Developed in 1964 by three groups of scientists:
Francois Englert and Robert BroutPeter HiggsGerald Guralnik, C. R. Hagen and Tom KibbleAll six physicists were jointly awarded the 2010 J. J. Sakurai Prize for Theoretical Particle Physics for this workSlide4
Sakurai prize winnersSlide5
The god particle
Peter Ware Higgs (1929)
Higgs bosons ‘’The most sought-after particle in modern physics’’
The only elementary particle predicted by the SM that has not been observed yetSlide6
Higgs mechanism
In SM it refers to the generation of masses for W and Z gauge bosons through electroweak symmetry breaking
The
higgs boson existence is not a necessary consequence of the HM Fermions can also acquire mass as a result of their interaction with the higgs field Slide7
