Neutrino-argon interactions in the T2K near detector — •Lukas Koch, Thomas Radermacher, Stefan Roth, and Jochen Steinmann — III. Physikalisches Institut B, RWTH Aachen

The T2K near detector employs three large, argon-filled TPCs with a total fiducial volume of about 10 m³ at ambient pressure. These TPCs have been exposed to the intense T2K muon-neutrino beam since the start of the experiment. The beam has a mean neutrino energy of 600 MeV and so far, data corresponding to over 6 · 10²⁰ (4 · 10²⁰) protons on target was recorded in neutrino (anti-neutrino) mode.

We expect about 600 charged current neutrino-argon interactions in the data. That enables us to do the world’s first neutrino-Argon cross section measurement in gaseous argon, thus making an important contribution to constraining nuclear interaction models for future neutrino oscillation measurements. This talk will describe the physics goals and present the current status of the analysis.
