Spring 2025 Undergraduate Research Program
Students in the N3AS undergraduate program work with a scientific mentor to develop their research, and also have a career mentor. Students are directly supported by N3AS, and participate in […]
Lepton Number Violating Neutrino Self-Interactions Heat Up proto-Neutron Stars
Neutrinos are the most intriguing particles whose masses point to the existence of new physics. They rarely interact; therefore, they can directly probe the most extreme environments and provide insights [...]
Sterile Neutrino Dark Matter Gets Even Cooler
We don’t yet know what makes up dark matter, but we do know that it doesn’t belong to the familiar particles of the Standard Model. One promising class of very well motivated dark matter candidates are dark neutral leptons, or “sterile neutrinos”.
Nuclear excited states may be key to search for new flavor-violating physics
Collider-based experiments continue to push the energy frontier in search of new particles.
