It will serve as a far detector, 295 km away, of a long baseline neutrino experiment for the upgraded J-PARC […]

Speaker: Adrien Hourlier (MIT) Title: MiniBooNE Oscillation Results with Complete Dataset Abstract: The MiniBooNE experiment, located on the Booster Neutrino Beamline at Fermilab, reports a total excess of 638.0+/-132.8 electron-like events (4.8σ) from a data sample corresponding to 18.75×10^20 protons-on-target in neutrino mode, which is a 46% increase in the data sample with respect to […]

Speaker: Scott Kravitz (LBNL)    Title: CrystaLiZe - Solid Xenon Detector R&D   Abstract:  Radon and its daughter decays limit the sensitivity of direct WIMP dark matter searches, despite extensive screening programs, careful material selection and specialized Rn-reduction systems. For xenon time projection chambers, a means to surpass this constraint may lie in crystallizing the xenon. In […]

Speaker: Tomi Akindele (Lawrence Livermore National Laboratory)  Title: Antineutrinos as a Nuclear Safeguards Tool Abstract: To date, antineutrino experiments built for the purpose of demonstrating a nonproliferation capability have typically employed organic scintillator, and been situated as close to the core as possible - typically a few meters to tens of meters distant, and have […]

Speaker: Anton Baleato Lizancos (Cambridge) Title: “Understanding biases to CMB lensing and delensing on the road to precision science” Abstract: For cosmologists, CMB lensing can be both a blessing and a nuisance. It's a nuisance because it generates spurious B-mode polarisation which obscures the highly-sought-after signal from inflationary gravitational waves, but it's a blessing because […]
