PhysicsPhysics
• Formulated the “quark model” of hadronic resonances.
• Identified the SU(3) flavor symmetry of light quarks.
• Created current algebra in 1960.• Responsible for see-saw theory of neutrino
masses.
Quark model
PhysicsPhysics
• Discovered the sigma model of pions.
• Kept string theory going throughout the 1970’s.
• With help of others they discovered, Quantum Chromodynamics.
• That was in 1984.
The Quark ModelThe Quark Model
•Elementary particle and a fundamental
constituent of matter.
• Quarks combine to form composite
particles called hadrons.
•There are six types of quarks
-up
-down
-charm
-strange
-top
- bottom
The Quark ModelThe Quark Model
• Up and Down has lowest masses.
• Charm, strange, top, and bottom only produced in..
• High energy collisions.
• (Involving cosmic rays and particle accelerators.)
The Quark ModelThe Quark Model
• Quarks have carious intrinsic properties.
-Electric charge
-Color charge
-Spin
-Mass
The Quark ModelThe Quark Model
• Classified as the Eightfold Way.
• Gell-Mann and George Zweig proposed it in 1964.
• It wasn’t until 1977 it was official.
• Named it after the sound made by ducks.
Murray Gell-MannMurray Gell-Mann
• Married in 1992, to Marcia Southwick.
• After she died he married again to J.Margaret Dow.
• Had 3 children.
• 1 girl and 2 boys.

• Girl: Elizabeth
• Boys: Nicholas Webster, (step son) Nicholas Southwick Lewis.
• Total of 30 awards/honors in lifetime.
• Knew 13 languages and spoke fluently.
