A smoking gun to hunt - Tradução em português

Peter Higgs at Edinburgh University was the first to point out in 1964 that a new particle, the eponymous boson, was a by-product of the mass-giving field. That was a crucial step, because it gave scientists a smoking gun to hunt for in their experiments. One of the original gang of six, Robert Brout at the Free University in Brussels, died last year. The others are Francois Englert from Belgium, Tom Kibble from the UK, and Dick Hagen and Gerry Guralnik in the US.
