Particle Physics Seminar

"Latest oscillation results from the NOvA experiment"

Presented by Diana Patricia Mendez, University of Sussex

Thursday, May 30, 2019, 3:00 pm — Small Seminar Room, Bldg. 510

NOvA is a long-baseline neutrino oscillation experiment measuring $\nu_{\mu}$ disappearance and $\nu_e$ appearance within the NuMI beam from Fermilab. The experiment uses a Near and a Far Detector placed 810 km away from each other and at 14 milliradians off the beam-axis resulting in an observed energy spectrum that peaks at 2 GeV, close to the oscillation maximum. A combined $\bar{\nu}_{\mu}$ + $\nu_{\mu}$ disappearance, and $\bar{\nu}_{e}$ + $\nu_{e}$ appearance result will be presented including NOvA's first collected anti-neutrino data for a total exposure of $16\times10^{20}$ protons-on-target. In addition to an increased exposure, an upgraded analysis has enable the experiment to set new limits to the allowed regions for $\Delta m^2_{32}$ and sin$^2\theta_{23}$ and make a measurement of $\Delta m^2_{32}$ among the world's best.
