Starting from the bottom

The bottom quark may lead physicists on a path to new discoveries. The Standard Model of particle physics has been developed over several decades to describe the properties and interactions of elementary particles. The model has been extended and modified with new information, but time and again, experiments have bolstered physicists' confidence in it. And yet, scientists know that the model is incomplete. It cannot predict the masses of certain particles, nor can it explain what most of the uni...
