Some of the most compelling questions in particle physics today are to do with the Higgs boson and supersymmetry (SUSY).
Read article 'Twenty-five years of neutral currents'
In the summer of 1973, an experiment at the Gargamelle bubble chamber at CERN discovered a new physics effect. Gordon Fraser looks back at how confirmation of the existence of neutral currents ushere...
