Spin Secrets Exposed: Scientists Unravel a Decades-Old Proton Mystery

A novel approach that re-examines observational data without relying on prior assumptions, using the framework of lattice QCD, provides strong evidence for a positive gluon spin, ∆g. For decades, researchers have sought to unravel the complex structure of the subatomic world. One particularly challenging question has been the origin of the proton’s intrinsic angular momentum, [...]
