K03.00001: Neutrino Experiments at the Frontier of the Search for New Physics Invited Speaker: Ian Shoemaker I will discuss the range of new physics that can be probed at present and upcoming neutrino experiments. In addition to new physics in the neutrino sector, neutrino experiments are at a level of sensitivity sufficient to probe a variety of other new physics such as axions and dark matter models.

K03.00002: Latest Oscillation Results from NOvA Invited Speaker: Gavin Davies NOvA is a long-baseline neutrino oscillation experiment. Its large tracking calorimeters can detect and identify muon and electron neutrino interactions with high efficiency. Neutrinos produced by the NuMI beam are detected by a near detector, located at Fermilab, and a much larger far detector, located 810 km away in Ash River, Minnesota. NOvA can measure the electron neutrino and antineutrino appearance rates, as well as the muon neutrino and antineutrino disappearance rates, in order to constrain neutrino oscillations parameters, including the large mixing angle $\theta_{23}$, the neutrino mass hierarchy, and the CP-violating phase $\delta_{CP}$. This talk will present NOvA's latest results combining both neutrino data ($13.6\times10^{20}$ POT) and antineutrino data ($12.5\times10^{20}$ POT). [Preview Abstract] |

K03.00003: First Results from NOvA's Magnetic Monopole Search Martin Frank The existence of the magnetic monopole has eluded physicists for centuries. The NOvA far detector (FD), used for neutrino oscillation searches, also has the ability to identify slowly moving magnetic monopoles ($v < c / 100$). With a surface area of 4,100 m$^2$ and a location near the earth's surface, the 14 kt FD provides us with the unique opportunity to be sensitive to potential low-mass monopoles unable to penetrate underground experiments. We have designed a novel data-driven triggering scheme that continuously searches the FD's live data for monopole-like patterns. At the offline level, the largest challenge in reconstructing monopoles is to reduce the 148,000 Hz speed-of-light cosmic ray background. In this talk, I will present the first results of the NOvA monopole search for slow monopoles. [Preview Abstract] |
