OPERA neutrino-induced charmed hadron event 237040910

Description

This OPERA detector event is a muon neutrino interaction with the lead target where a charmed hadron was reconstructed in the final state. The event data consist of Electronic Detector files (such as Drift Tube, RPC, and Target Tracker files) and Emulsion Detector files (such as Tracks and Vertex files). For more information, see the description of the whole dataset.
