Particle Discovery Lab: CMS Open Data in undergraduate physics courses

High energy physics data analysis can provide a valuable learning experience in undergraduate physics courses. We present a "Particle Discovery Lab", in which students learn to analyze and interpret data as they discover a fundamental particle. The exercise is primarily targeted for intermediate-level modern physics courses, but now also includes a "Higgs Boson expansion". CMS Run 1 data from the CERN Open Data Portal was analyzed using cloud computing tools to produce a 4-lepton dataset in which students can rediscover the Higgs boson. This option is available for the intermediate-level lab exercise, and a more comprehensive analysis exercise has been developed for upper-level experimental courses. The Particle Discovery Lab, including the Higgs Boson expansion, is accessible to instructors via the Open Data Portal.
