SUMMARY

The discussion centers on the mass difference between neutrons and protons, specifically questioning if the difference can be attributed to the mass of a down quark. It is established that a proton consists of two up quarks (uud) and a neutron consists of one up quark and two down quarks (udd). The conversation highlights that while the mass difference between the neutron and proton is relevant, other interactions contribute to this discrepancy, complicating the calculation of individual quark masses.

PREREQUISITES
  • Understanding of quark composition (uud for protons, udd for neutrons)
  • Basic knowledge of particle physics
  • Familiarity with mass-energy equivalence
  • Concept of quantum chromodynamics (QCD)
NEXT STEPS
  • Research the role of quantum chromodynamics (QCD) in particle mass
  • Study the mass-energy equivalence principle in detail
  • Explore the interactions affecting quark masses
  • Learn about the Standard Model of particle physics
USEFUL FOR

Students of physics, particle physicists, and anyone interested in the fundamental components of matter and their interactions.

I don't know much about quarks but if a proton is uud and a neutron is udd, is the (mass of a neutron)-(mass of proton)=mass of a down quark?

More like u-d.
 


Right, sorry...
 


neutron-proton would be d-u, but other interactions also contribute to the mass difference. It can get complicated.
