The Deep Underground Neutrino Experiment is an international experiment to unlock the mysteries of neutrinos. DUNE will be installed in the Long-Baseline Neutrino Facility, under construction in the United States. One mile underground, at the Sanford Underground Research Facility in South Dakota, the excavation of the large LBNF caverns for the DUNE far detectors is in full swing. When complete, the LBNF underground facility will cover an area about the size of eight soccer fields.
Dark matter is invisible; it’s everywhere; and it doesn’t interact with matter very often. The same is true for neutrinos. So are neutrinos dark matter? Neutrino physicist Kirsty Duffy and neutrino/dark matter researcher Asher Kaboth (Royal Holloway, University of London) break down the most likely dark matter candidates and where neutrinos fit into the mix.
Using Newtonian physics, physicists have found an expression for the value of kinetic energy, specifically KE = ½ m v^2. Einstein came up with a very different expression, specifically KE = (gamma – 1) m c^2. In this video, Don Lincoln shows how these two equations are the same at low energy and how you get from one to the other.
On July 4, 2012, researchers at the CERN laboratory in Europe announced the discovery of the Higgs boson. It was a tremendous triumph for the Standard Model of particle physics and confirmed a prediction made nearly half a century prior. In 2022, we celebrate the 10th anniversary of that momentous discovery.
