<DIV><P>The discovery of the Higgs boson has brought us a giant step closer to understanding the fabric of our universe. But <I>before </I>the Higgs was found, its existence was hotly debated—and only a multi-billion-dollar machine could resolve the many vying theories on this fundamental question: <I>Why do some particles have mass?</I></P><P>In this first insider account of the spectacular inaugural experiments at the Large Hadron Collider, physicist Jon Butterworth captures a moment unlike any other in the annals of science—when the entire field of particle physics hinged on a single theory, and one experiment would prove or disprove the life’s work of the world’s most esteemed theoretical physicists. <I>Most Wanted Particle </I>deftly chronicles how scientists “replayed” the Big Bang by smashing subatomic particles at unthinkable speeds—and explains why, after our first glimpse of the Higgs, physics will never be the same.</P></DIV>
