Neutrinos are some of the most abundant, elusive, and exciting of all the fundamental particles. Their ability to oscillate between flavors — indicating that they have non-zero mass — is the only known evidence of physics beyond the Standard Model, and some theories predict that differences in the oscillation of neutrinos and antineutrinos could help explain why the universe is made of matter and not antimatter (or even why it exists at all). One of the biggest challenges for these measurements will be understanding how neutrinos interact with nuclei. Because neutrinos are light, neutral particles they are impossible to see in particle detectors; we have to study them indirectly through the charged particles produced when a neutrino interacts with atoms inside the detector. A good understanding of how exactly neutrinos interact is therefore vital to answer deeper questions about the fundamental physics of these particles. In this lecture I will discuss how we can measure neutrino interactions, what we know (and what we know we don’t know!), and where the main challenges are. This will be presented from an experimental perspective, featuring some highlighted results from cutting-edge experiments in the field.
This will be a hybrid seminar. For those who would like to attend in person, we have reserved the Hornets’ Nest (WH8X); please follow the Fermilab COVID requirements, including wearing a face covering. Zoom connection details and instructions can be found at the bottom of this email. In the interest of a productive seminar, we would appreciate it if you review the guidelines below.
