SUMMARY

This discussion centers on the numerical coincidence between neutron and proton masses, specifically the values of neutron mass (mN: 939565420.52 MeV) and proton mass (mP: 938272088.16 MeV). The difference in mass (Δm = mN - mP = 1,293,332.36 MeV) leads to intriguing calculations, such as mP - 3·Δm and mN - 4·Δm both equating to 934,392,091.08 MeV. Participants are encouraged to explore the implications of these calculations and seek out relevant academic papers for further understanding.

PREREQUISITES
  • Understanding of particle physics terminology, specifically mass measurements in MeV.
  • Familiarity with basic equations involving mass differences in nuclear physics.
  • Knowledge of neutron and proton properties and their significance in atomic structure.
  • Ability to interpret scientific papers and research related to particle mass calculations.
NEXT STEPS
  • Research academic papers on neutron and proton mass discrepancies.
  • Explore the implications of mass differences in nuclear reactions.
  • Investigate the role of mass in particle physics and its effects on atomic stability.
  • Learn about advanced topics in particle physics, such as quantum chromodynamics.
USEFUL FOR

Physicists, students of nuclear physics, and researchers interested in particle mass calculations and their implications in theoretical physics.

TL;DR
mP - 3·Δm = mN - 4·Δm = 934,392,091.08 eV/c^2
I can't possibly be the first to notice this numerical coincidence, but my search skills are inadequate to find information about it, and I was hoping others could point me toward papers on the subject.

Neutron mass, mN: 939565420.52 (54)
Proton mass, mP: 938272088.16 (29)
[https://physics.nist.gov/cgi-bin/cuu/CCValue?mnc2mev|ShowSecond=neutron+mass+in+MeV&First=mpc2mev]

Δm = mN - mP = 1,293,332.36
mP - 3·Δm = 934,392,091.08
mN - 4·Δm = 934,392,091.08

What's going on, there?
