THE PROTON. “The structure of the proton is a prototypical example of a strongly coupled and correlated system with quarks and gluons interacting according to quantum chromodynamics (QCD). At large energy and momentum scales, the interaction is relatively weak, whereas at lower energy scales the picture is clouded by the increasingly strong interaction.” https://www.nature.com/articles/s41586-021-03282-z View in LinkedIn

MATTER ASYMMETRY. “These results are expected to revive interest in several proposed mechanisms for the origin of this antimatter asymmetry in the proton that had been disfavoured by previous results, and point to future measurements that can distinguish between these mechanisms.” https://www.nature.com/articles/s41586-021-03282-z View in LinkedIn

ACTUAL QUARK ANTI-QUARK PAIRS. “Here we provide evidence from muon pair production measurements that these distributions are considerably different, with more abundant down antimatter quarks than up antimatter quarks over a wide range of momenta.” https://www.nature.com/articles/s41586-021-03282-z View in LinkedIn

ASSUMED QUARK ANTI-QUARK PAIRS. “In this picture of quark–antiquark creation by the strong force, the probability distributions as a function of momentum for the presence of up and down antimatter quarks should be nearly identical, given that their masses are very similar and small compared to the mass of the proton.” https://www.nature.com/articles/s41586-021-03282-z View in LinkedIn

STRANGE MASS. “The two up quarks and the single down quark that comprise the proton in the simplest picture account only for a few per cent of the proton mass, the bulk of which is in the form of quark kinetic and potential energy and gluon energy from the strong force.” https://www.nature.com/articles/s41586-021-03282-z View in LinkedIn
