Electronic detector data for multiplicity studies

It contains 817 muon neutrino interactions with the lead target where a muon was reconstructed in the final state. This happens in the so-called charged-current interactions of a muon neutrino.

For this data sample, the Collaboration performed a dedicated analysis, with a detailed classification of all particles produced at the neutrino interaction on top of the muon. Indeed, in a muon neutrino interaction with the nucleons of the lead target, different hadrons are produced: the so-called shower hadrons and nuclear fragments produced in the break-up and in the evaporation of the target nucleus. The detailed study of the multiplicity of the hadrons produced provides insights on the mechanism of the hadronic shower formation.
