摘要

Subatomic particles interact with different kinds of forces (strong, electromagnetic, weak and gravitational). In case of the weak force, the interaction is due to the exchange of intermediate charged (W~(+,-)) and neutral (Z~0) bosons. These cases are referred to as "charged currents" and "neutral currents", respectively. When evidence for such 'Weak neutral currents' was first published in 1973 the high energy physics community was incredulous.rnIt took the community a year to acknowledge the discovery. But this discovery, perhaps the most important made at CERN, was the onset of a new era in our understanding of fundamental interactions. Thirty-six years after the discovery, the 2009 EPS Prize for High Energy and Particle Physics was awarded to the Gargamelle Collaboration for the observation of the weak neutral current interaction.
