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.

Histograms: Uncertainty

Students construct histograms, identify the best value to represent the data, and report the uncertainty in their answers. 

Histograms: The Basics

Students build basic histogram skills required in many of the other activities in the Data Activities Portfolio.

What Heisenberg Knew

Heisenberg knew that, at the quantum level, we cannot know everything, at least not all at once. Students explore uncertainties in measurements of complimentary variables to find this out for themselves.

Mean Lifetime Part 3: MINERvA

Students collect data from muons which decay in the MINERvA detector in the Fermilab NuMi beamline to understand particle decay and determine the muon lifetime.

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.

Mean Lifetime Part 1: Dice

Rolling dice serves as the model for decaying particles.

Signal and Noise: Cosmic Muons

In this introductory tutorial that, students learn about how to distinguish muon signals from background and instrumental noise.

Signal and Noise: The Basics

Students analyze signals and noise first in audio and video forms and then look at signals and noise from physics measurements.
