Future detectors, such as Fermilab’s own DUNE, will be designed with proton decay searches in mind. Chris Marshall will present MINERvA’s precision measurement on charged-current kaon production — a significant background to the presumed method by which protons decay — at Friday’s Wine and Cheese seminar.

Physics is a holistic science in which we consider not only the individual parts but also how these parts combine into groups. Nucleons, or protons and neutrons, combine in groups to form atomic nuclei. The differences between how free nucleons behave and how nucleons inside a nucleus (bound nucleons) behave are called nuclear effects. In the past, scientists… More »

It can be hard to detect the ghostly neutrino, which rarely interacts with matter. To overcome this, neutrino experiments use detectors made of neutrons and protons bound up in heavy nuclei. The way these nuclei affect the particles made by neutrino interactions is not well understood, so MINERvA is working to measure this in as many ways as… More »

All particle physics experiments rely on computer simulations of their detectors to make measurements, but neutrino experiments struggle to test these simulations using particles that are created from the neutrino beam itself. Neutrino interactions often produce charged particles such as muons or electrons, and they knock one or more protons or neutrons out of the nucleus. Neutrino interactions also produce quark-antiquark pairs called pions (see earlier MINERvA results from February, August and… More »
