How do today's scientists use conservation of momentum?

Looking at the Data Plots

This data plot, a working document for your analysis, shows the debris known to be the signature of the top and antitop decay.

Get to know the particles recorded in the data plot!

Four "jets" – large blasts of particles – (red and blue towers). One of the jets will often contain a low energy or "soft" muon (dotted green line).

A muon. (green tower)

A neutrino. While scientists can predict with confidence that a neutrino comes out of the collision, it cannot be detected very easily.
