Evidence for intrinsic charm quarks in the proton "Here we provide evidence for intrinsic charm by exploiting a high-precision determination of the quark–gluon content of the nucleon3 based on machine learning and a large experimental dataset." https://www.nature.com/articles/s41586-022-04998-2 https://www.nature.com/articles/s41586-022-04998-2 this is a tentative model of a Machine Learning "thought experiment". physical observation of the phenomenon must be confirmed before this is cannonized as scientific fact.
