The hunt for the Higgs particle has involved the biggest, most
expensive experiment ever. So exactly what is this particle? Why
does it matter so much? What does it tell us about the Universe?
Did the discovery announced on 4 July 2012 finish the search? And
was finding it really worth all the effort? The short answer is
yes. The Higgs field is proposed as the way in which particles gain
mass - a fundamental property of matter. It's the strongest
indicator yet that the Standard Model of physics really does
reflect the basic building blocks of our Universe. Little wonder
the hunt and discovery of this new particle produced such intense
media interest. Here, Jim Baggott explains the science behind the
discovery, looking at how the concept of a Higgs field was
invented, how the vast experiment was carried out, and its
implications on our understanding of all mass in the Universe.
