Uncover the fascinating journey behind the LBNF-DUNE project, where scientists, engineers, and construction workers are excavating 800,000 tons of rock to pave the way for groundbreaking neutrino research. Delve into the mysteries of these elusive subatomic particles and how their behavior may hold the key to understanding the imbalance between matter and antimatter in the universe. With insights from the Department of Energy’s Office of Science, this blog post explores the ambitious goals and potential discoveries of the LBNF-DUNE experiment.

Breaking Ground on Neutrino Detection
Visualize the situation of digging a hole in your back yard and counting on to dig further until you reach China or Australia — sounds stupid because it indeed is. Yet the project scientists, engineers, and construction workers for LBNF-DUNE have taken on a challenge at least as daunting — albeit one that will pay big dividends in scientific discovery.
So, they’ve burrowed 800,000 tons of rock out of the Sanford Underground Research Facility in Lead, South Dakota in preparation to build the largest and most ambitious experiment in neutrinos yet. Inside these huge caverns, a giant particle detector will be positioned along with the necessary equipment to attempt to solve some of Physics’ greatest unsolved mysteries.
Neutrinos: A Broader Perspective
Circular: Neutrinos, subatomic particles that have mystified physicists for almost a century following their initial detection in the 1930s. One of the major surprises was the revelation that neutrinos have mass, against expectations from the Standard Model of Particle Physics. Physical are now endeavoring to understand the fine points of neutrino mass and how these devious particles can circumvent the rules of our reigning theory of everything.
One of the most remarkable things they found was that neutrinos can oscillate between three types as they fly. This feature is one of the main reasons that physicists are so keen on studying these particles, as they argue it could help explain why there is more matter than antimatter in the universe. The LBNF-DUNE experiment seeks to answer this fundamental physics question by observing how neutrinos and their antimatter partners, antineutrinos, oscillate from one type into another as a function of time.
Neutrinos, and the universe’s secrets
In addition to probing the mysteries of neutrinos, the LBNF-DUNE project has the potential produce interesting results on other fronts. For example, when stars die and go supernova, they release a flood of neutrinos. How LBNF-DUNE detectors could, theoretically, help researchers see some of the messy activities happening inside those cosmic disasters as they are fueled by neutrinos.
The LBNF-DUNE experiment is also designed to look for the possible decay of protons, the only composite particles we know of that don’t spontaneously come apart. Observing this process could provide insights into the very basic properties of the universe, suggesting whether or not there was ever one single force, and if how those four forces we know today emerged from since the time of Big Bang. The revelation might also explain the eventual fate of the universe.
