“You can have a component of the proton which is heavier than the proton itself.”
Rojo and colleagues combined a variety of experimental results and theoretical calculations in hopes of unveiling the proton’s hypothetical charm. Measuring this feature is key to fully understanding one of the most important particles in the universe, Rojo says.
of transient quarks and their antimatter counterparts, antiquarks . Such “extrinsic” quarks are created when gluons, particles that help “glue” the quarks together inside protons, split into quark-antiquark pairs. In quantum physics, particles don’t take on a definite state until they’re measured — they are instead described by probabilities. If protons contain intrinsic charm, there’d be a small probability to find within a proton not only two up quarks and a down quark, but also a charm quark and antiquark. Since protons aren’t well-defined collections of individual particles, a
Using thousands of measurements from experiments at the LHC and other particle accelerators, combined with theoretical calculations, the team found evidence for intrinsic charm in the proton at a statistical level called 3 sigma. The intrinsic charm quarks carry about 0.6 percent of a proton’s momentum, the researchers report.
