Long-lived physics

New particles produced in the LHC's high-energy proton-proton collisions don't hang around for long. A Higgs boson exists for less than a thousandth of a billionth of a billionth of a second before decaying into lighter particles, ...

Open-source software for data from high-energy physics

Most of the universe is dark, with dark matter and dark energy comprising more than 95 percent of its mass-energy. Yet we know little about dark matter and energy. To find answers, scientists run huge high-energy physics ...

SLAC particle physicist discusses the search for new physics

The Standard Model of particle physics describes the properties and interactions of the constituents of matter. The development of this theory began in the early 1960s, and in 2012 the last piece of the puzzle was solved ...
