In March 2021, the TOTEM collaboration at CERN and the D-Zero collaboration at Fermilab jointly announced the discovery of the "odderon" particle, a color-neutral gluonic state. The purpose of this tutorial is to help teachers present this important discovery to their students.

Workshop Tutorial for Teachers

Divide into groups. Each group is assigned 1-2 questions. Discuss results.

Questions:

1. What are gluons?
2. What is an odderon? How can its effects be observed?

Each group reports out their findings.
