Evidence for intrinsic charm quarks in the proton - Nature.com

Through machine learning analysis of a large set of collider data, a study disentangles intrinsic from radiatively generated charm, and finds evidence for an intrinsic charm quark within the proton wavefunction.

The foundational deep-inelastic scattering experiments at the SLAC linear collider in the late 1960s and early 1970s demonstrated the presence inside the proton of point-like constituents, soon ident… [+18413 chars]
