New 3-flavor neutrino oscillation results from NOvA

US/Central
Description

Code of conduct: The Wine and Cheese is a scientific seminar and thus questions and discussion are welcome. The goal of discussion is to enhance the quality and understanding of the science for the whole community. Out of consideration for all, even when questions are not straightforward, we will insist that they be asked and answered with respect and civility. We value voices of all backgrounds, accents, pitches and degrees of softness, both among our speakers and in the audience. Scientific claims are judged by their content and rigor, and not by the demeanor of their proponent

      New 3-flavor neutrino oscillation results from NOvA 1h

      NOvA, celebrating its 10th anniversary of data collection in 2024, is one of only two long-baseline accelerator neutrino experiments currently operating worldwide. Using Fermilab's powerful NuMI beam and two functionally identical tracking calorimeter detectors, NOvA can observe muon neutrino (and antineutrino) disappearance and electron neutrino (and antineutrino) appearance. By comparing the near detector's measurements of the unoscillated beam with the far detector's data, NOvA precisely measures the larger neutrino mass splitting and sets constraints on parameters of the PMNS mixing matrix. In this seminar, we will present the results of the latest oscillation analysis, featuring a new low-energy electron neutrino sample and doubled neutrino-mode beam exposure.
