Neutrino-hydrogen interactions with a high-pressure time projection chamber

Understand

We investigate the idea of detecting pure neutrino-hydrogen interactions in a multinuclear target using the transverse kinematic imbalance technique [Lu et al., Phys.

• D 92, 051302 (2015)] in a high-pressure time projection chamber (HPTPC).
• With full solid-angle acceptance, MeV-level proton tracking threshold, state-of-the-art tracking resolution, and an O(100 m^3) gas volume at 10 bar, an HPTPC could provide an opportunity to realize this technique.
