The proton charge radius puzzle exists because the proton charge radius appears different when measured with electrons than when measured with muons. "Ordinary" explanations include problems with the extrapolations or theoretical corrections involved in the measurements, and "exotic" explanations include such beyond the standard model ideas as a breakdown of electron-muon universality. We will discuss possibilities in both categories.
