Particle Trappin'

Earn Einstein Bucks. Fill in the form below. You can always go back to the window with the calorimeter to check how it works.

Particles trapped in lead: pions electrons

Particles trapped in uranium: pions electrons

Least number of slabs of lead needed to measure 45 Gev particles:

Least number of slabs of uranium needed to measure 45 Gev particles:

To double your bucks, answer the following:

Each Z can decay into two pions or two electrons. Each pion or electron has an energy of about 45 GeV.
About how much do you think the mass of the Z is?
45  90  180
