Now in paperback: the ivid account of what the process of discovery was really like for an insider.?Peter Higgs Particle physics as we know it depends on the Higgs boson: It the missing link between the birth of our universes a sea of tiny, massless particlesnd the tangible world we live in today. But for more than 50 years, scientists wondered:Does it exist? Physicist Jon Butterworth was at the frontlines of the hunt for the Higgs at CERN Large Hadron Collidererhaps the most ambitious experiment in history. InMost Wanted Particle, he gives us the first inside account of that uncertain time, when an entire field hinged on a single particle, and life at the cutting edge of science meant media scrutiny, late-night pub debates, dispiriting false starts in the face of intense pressure, and countless hours at the collider itself. As Butterworth explains, our first glimpse of the elusive Higgs brings us a giant step closer to understanding the universend points the way to an entirely new kind of physics.
