Pershing Abstract
NOvA is a two-detector, long-baseline experiment designed to measure the rate
of electron neutrino appearance in the narrow-band, off-axis NuMI beam of
muon neutrinos. We will discuss recent results from the joint analysis of
muon neutrino disappearance and electron neutrino appearance. The dataset
includes 9.48e20 protons-on-target, all with the beam in neutrino running.
Additionally, we will cover a cross section analysis of neutral pion
production in charged current events, measuring the differential kinematic
distributions in such interactions. This interaction channel is a background
to electron neutrino appearance searches and is thus very relevant to current
and future oscillation experiments.

Yuan Abstract
The IceCube Neutrino Observatory, a cubic-kilometer in-ice detector at the South Pole, offers a
unique window into the smallest and largest scales of our universe. Over the past several years,
IceCube has detected the first high-energy neutrinos of astrophysical origin, measured
atmospheric neutrino oscillations, and performed searches of neutrino sources throughout the
sky. As more data is collected, better detector modeling and systematic uncertainties becomes
ever more important for neutrino astronomy and neutrino property measurements in IceCube.
In this talk, I will discuss recent improvements for the high-energy starting event (HESE) analysis
with 7.5 years of data. These include a more accurate atmospheric neutrino background
calculation, a new likelihood description that correctly accounts for Monte-Carlo statistical
uncertainties, and updated reconstructions with better ice modeling. In this context, I will show
new results for the diffuse astrophysical flux spectrum, flavor composition, as well as several
new physics measurements using the HESE sample.
