About BAM

The Big Analysis of Muons (BAM) is a project based on simplified LHC masterclasses in two flavors: ATLAS and CMS.  Each retains most of the interesting parts of the corresponding masterclass used in International Masterclasses (IMC) but is simple enough to explain to students via screencasts, text, and online discussion. BAM has two purposes: to give students a meaningful masterclass experience while studying at home and reach students and teachers who might not ordinarily participate in IMC using online tools.

How it works

  1. Contact your students who might want to participate in an online masterclass and register by Tuesday 18 May. (Registration is now closed.)
  2. We will have a two Teacher Q&A videoconferences on the BAM Zoom Channel - one for ATLAS and one on CMS in the week of 16 May. Further information on Zoom can be found on this page. (Ignore the parts about MINERvA - they are for a different masterclass.)
  3. At your discretion, you can offer prep activities that work via remote learning. Suggestions are below. Rolling with Rutherford and The Particle Adventure are especially recommended. Both can be done online.
  4. Study the ATLAS and CMS student pages and then send your students there to learn what they will do in the masterclass. These include screencasts to cover all aspects of BAMC that students need on that page along with the text.
  5. Datasets are now available on the BAM Data Assignments page. Each data file should have two students assigned to it. Students should collaborate online so they can work together on the analysis. Students are expected to facilitate their own commication in pairs but the teacher can also assign school-provided online tools. If neither is a good option, please contact Ken or Shane for help.
  6. Have your own videoconference with your students who are interested in participating to explain BAM and point out resources like the Student Prep activities below and the ATLAS or CMS page. Stress that students need to watch the screencasts on their student page to understand how to do the measurement.
  7. A talk on the Standard Model and the experiment they will study will be available for students on Monday 24 May, at 13:00 UTC for CMS and 19:00 UTC for ATLAS.  These will be carried in a special Zoom webinars. We may need to place limits on the number of students each teacher can bring. We will keep you informed about this.  
  8. Student data analysis can be started once you think your students are ready. Often, students start after the talk. Please work out the logistics with them and be available for their questions. 
  9. The masterclass videoconferences will take place on Wednesday 26 May. Zoom webinars will be established for ATLAS and CMS webinars. 
  10. All videoconferences and webinars are password-protected. You will get a password to log in which you can share with your students.
  11. Advice from teachers on all of the above is very valuable. Please contact Shane or Ken with questions, concerns, and ideas.


Student Prep

There are several activities that students can do at home from the QuarkNet Data Activities Portfolio that will help. You can assign or suggest some of these to help them prepare. They have each have comments on how to extend them for study at home, where needed. They are:

In addition, we suggest The Particle Adventure for an overview of particle physics and, for further study, the videos by Don Lincoln on Fermilab YouTube Channel.
