MicroBooNE measures charged-particle multiplicity in first neutrino-beam-based result

This plot shows the azimuthal angle difference distribution for events with an observed multiplicity of two for data (points with error bars) and model (histogram). The peaks near positive and negative pi indicate presence of the quasielastic scattering process, while the distribution between the peaks is consistent with predicted contributions from resonance production. The shaded blue area is the estimated cosmic ray background.

MicroBooNE’s first neutrino-beam-based physics result, submitted to the journal Physics Review D this spring, launches the experiment’s journey along this path.
