# CMS Masterclass WZH-path

Students are physicists for a day at a university or lab where they work with physicists to learn how to analyze real particle physics data in the form of event displays.

# Energy, Momentum, and Mass

Students examine data to find how energy, momentum, and mass are related.

# The Case of the Hidden Neutrino

Students use momentum conservation to examine the decay of top-antitop pairs to determine what is missing from the event.

# CMS Masterclass J/Psi

Students are physicists for a day at a university or lab where they work with physicists to learn how to analyze real particle physics data in the form of event displays.

# ATLAS Data Express

ATLAS Data Express is a short investigation in which students inspect and characterize Z events in the LHC and distinguish muons from electrons.

# TOTEM Data Express

Use quantum physics and LHC data to estimate the size of the proton.

# CMS Data Express

CMS Data Express is a short investigation in which students inspect and characterize W or Z events from the LHC.

# Calculate the Top Quark Mass

Students use conservation laws and vector addition to calculate the top mass from event displays.

# Calculate the Z Mass

Students use conservation laws and vector addition to calculate the Z mass from event displays.
