Inside the proton, the ‘most complicated thing you could possibly imagine’ (quantamagazine.org)

Article summary

Researchers have made new discoveries about the proton, finding that it sometimes includes a charm quark and charm antiquark, which are heavier than the proton itself. The proton is a complex and mysterious particle that exists as a haze of probabilities until an experiment forces it to take a concrete form. Physicists are still working to fully understand the proton, using experiments and simulations to uncover its secrets. The proton's complexity is due to its composition of quarks and gluons, which interact with each other in complex ways.

What commenters say

• The proton's complexity is not surprising given its composition of quarks and gluons.
• The discovery of charm quarks in the proton is not unexpected, but rather a confirmation of theoretical predictions.
• The idea that a neutron is a proton with an electron stuck inside it is a misconception.
• The conversion of one elementary particle into another is a complex process that is not fully understood.
• The existence of a charm asymmetry in the proton is an open question.
• The proton's complexity is a challenge for experimental physics, requiring high-luminosity colliders to probe its properties.
• Theoretical models of the proton, such as quantum chromodynamics, are essential for understanding its behavior.
• The proton's properties are still not fully understood, and further research is needed to uncover its secrets.
