What If Charge is NOT Fundamental?

PBS Space Time11 minutes read

Electric charge is a fundamental property connected to isospin and hypercharge in particles, leading to the understanding that it is a combination of both. The weak force acts on left-handed particles through weak isospin and weak hypercharge, fundamental properties of elementary particles like quarks and electrons.

Insights

  • Isospin and hypercharge are conserved quantities that, when combined, help explain the relationship between protons, neutrons, and electric charge in particles, leading to the understanding that electric charge is a combination of these two properties.
  • The discovery of geometric patterns in particles based on isospin and hypercharge by Murray Gell-Mann not only led to the prediction and discovery of the omega baryon but also indicated that nucleons are composed of smaller components called quarks, showcasing the intricate nature of particle physics.
