About these units
Muon Mass (mᵤ)
The muon is a heavier cousin of the electron, with a mass of about 1.8835316 × 10⁻²⁸ kilograms, roughly 207 times more massive than the electron. Because the muon behaves like an electron but with much greater mass, it offers unique opportunities for probing fundamental physics. Muonic atoms—where a muon replaces an electron—allow extremely precise measurements of nuclear size due to the muon's tighter orbit. Muons are also produced naturally in Earth's atmosphere from cosmic rays and are widely studied in particle accelerators. Research into muon behavior has led to major discoveries, and the muon mass continues to attract interest in tests of physics beyond the Standard Model.
Proton Mass (mₕ (p))
The proton mass, approximately 1.67262192369 × 10⁻²⁷ kilograms, is central to chemistry, nuclear physics, and cosmology. Protons, along with neutrons, form the nuclei of atoms and therefore compose most of the mass of ordinary matter. The proton mass arises from the strong nuclear force and the dynamics of quarks and gluons within quantum chromodynamics (QCD). Interestingly, most of the proton's mass is not from its constituent quarks but from the energy stored in the strong force. Understanding the proton mass helps scientists explore nuclear stability, binding energies, and stellar nucleosynthesis—the processes that form elements inside stars.
