Lets slow down for a moment.
A proton is a particle that, along with neutrons and electrons, makes up an atom.
Protons themselves are made of even tinier particles called quarks.

These quarks glom together thanks to the strong force, one of thefour fundamental forces.
(The other three are gravity, the weak force, and electromagnetism.)
Publishedin Reviews of Modern Physics, the work follows up on a2018 measurementof the protons internal pressure.
In DVCS, a high-energy electron is beamed at a target hydrogen proton.
A quark within the proton emits a photon, which carries information about the quarks properties.
The data collection was something of an accident.
It has already changed the way we think about the structure of the proton.
In other words, DVCS could be an avenue for the discovery of new physics.
Next, the team plans to take new measurements of the size of the proton.
