"Sterile Neutrino Search in MINOS+ via Electron Neutrino Appearance"

10:00am, RLM 9.222

Abstract: MINOS+, the successor of the MINOS experiment, has taken data from September 2013 to July 2016. Utilizing the Fermilab NuMI beam operating in the medium energy setting, MINOS+ analyses aimed to not only cross-check the MINOS results on the conventional three-flavor model but also search for the possible existence of sterile neutrinos and other exotic phenomena. By conducting the electron neutrino appearance analysis within the framework of a 3+1 model, new limits on the sterile mixing angle $sin^2(2theta_{mu e})$ regarding various values of the mass-squared different $Delta m^2_{41}$, can be set, allowing a direct comparison to the LNSD anomaly.
