Neutrino Cross-Section Measurements in Argon Gas

by Dr. Pip Hamilton

Achieving the high precision measurements necessary to complete our picture of the PMNS matrix will require precise measurements of neutrino-nucleus cross-sections to complement the next generation of long-baseline oscillation experiments. Many tensions between our current nuclear models are only apparent in the lowest-energy nuclear ejecta, to which most neutrino detectors are insensitive. Looking for neutrino interactions in a gaseous medium allows us to see particles down to lower energies than any other detector technology. In this talk I will present the work done at T2K in making a first measurement of neutrino-nucleus interactions in gas, and discuss the potential of gaseous detectors for future neutrino experiments.
