The subatomic world is governed by three known forces, each with vastly different energy. In this video, Don Lincoln takes on the weak nuclear force and shows why it is so much weaker than the other known forces.
Weak force decays change the identity of a particle as well as its electrical charge. Scientists are looking for identity-changing decays with no change in electrical charge, which would point to new physics.
Scientists of the DZero collaboration at the Department of Energy’s Fermi National Accelerator Laboratory announced in a seminar at Fermilab on December 8, 2006 the first evidence of single top quarks produced in a rare subatomic process involving the weak nuclear force.
