The LHC-watcher's field guide

These are the event displays of Large Hadron Collider physicists' dreams. Our current understanding of particle physics, known as the Standard Model, has been tremendously successful. Over the past 40 years, it has pointed experimentalists toward many a discovery, such as the Higgs boson in 2012. However, despite all of its triumphs, there are a few things that the Standard Model does not explain. One major missing piece, for example, is gravity. Although gravity is one of the four fundamental f...
