By Design: Unlocking the Mysterious World of Quarks in Particle Physics

Quarks are elementary, subatomic particles that form the framework for our understanding of the fundamental constituents and forces of the <a href="https://home.cern/science/physics/standard-model" rel="noopener ugc nofollow" target="_blank">Standard Model </a>of particle physics. In 1964, physicists Murray Gell-Mann and George Zweig were working independently on a theory for strong interaction symmetry in particle physics. But it wouldn’t be until 1968 that the confirmation of quarks came through a series of experiments conducted by Richard Feynman and others. <a href="https://www.nobelprize.org/uploads/2018/06/kendall-lecture-1.pdf" rel="noopener ugc nofollow" target="_blank">Deep inelastic scattering experiments</a> provided indirect evidence supporting the existence of quarks. In 1974, experiments at the <a href="https://www6.slac.stanford.edu/" rel="noopener ugc nofollow" target="_blank">Stanford Linear Accelerator Center (SLAC)</a> provided conclusive evidence for the existence of quarks. The experiments involved scattering high-energy electrons off protons, and the results were consistent with the presence of point-like constituents within the protons, confirming the quark model. <a href="https://medium.com/intuition/by-design-unlocking-the-mysterious-world-of-quarks-in-particle-physics-8fa306438b9e">Learn More</a>
