Dimuon	Dimuon A dimuon or "dimuon pair" is a muon-antimuon pair that results from a particle decay. For example, the Z boson can decay into dimuons. A Z boson can decay to a dimuon pair.
Muon	Muon The muon (from the Greek letter μ) is an elementary particle similar to but much more massive than the electron. The muon has electric charge -1 and a spin 1/2; an antimuon is the same but with charge +1. The muon is classified, with the electron, the tau, and the neutrinos, as a lepton. Leptons are fundamental particles that do not interact via the strong force. The muon (circled in red) in the Standard Model chart.
abstract	Abstract: An abstract is a shortened version of the paper and should contain all information necessary for the reader to determine: what the objectives of the study were; how the study was done; what results were obtained; and the significance of the results.
metadata	Metadata (meta data, or sometimes metainformation) is "data about other data". The e-Lab stores metadata for the Cosmic Ray data files, plots and posters. Searching metadata is a powerful way to find the data you want. Read more about metadata on Wikipedia.
milestone	Scientists have software to plan and track their projects. Our online version includes these milestones with references and a logbook that allow you to plan and track your work. The color of the dot indicates where on the site you will be working for that milestone (for example, blue dots correspond to the Data section).
milestone seminar	Scientific collaborations hold regular meetings to track progress on their projects. Leaders also schedule impromptu meetings for smaller groups focused on an aspect of the larger project. Teachers may hold milestone seminars to discuss your progress and understanding.
