What is the quark model in nuclear physics?
Quark models are a successful tool used in physics for classifying and interpreting light hadrons, predicting key features of mesons and baryons, and aligning with the partonic description of deep inelastic phenomena.
What is strange about the strange quark?
What makes strange quarks different from down quarks–apart from having 25 times the mass of down quarks–is that they have something that scientists call "strangeness." Strangeness is basically a resistance to decay against strong force and electromagnetism.
What is the quark model of matter?
The quark model was independently proposed by physicists Murray Gell-Mann and George Zweig in 1964. Quarks were introduced as parts of an ordering scheme for hadrons, and there was little evidence for their physical existence until deep inelastic scattering experiments at the Stanford Linear Accelerator Center in 1968.
How was the quark model discovered?
Quarks are widely recognized today as being among the elementary particles of which matter is composed. The key evidence for their existence came from a series of inelastic electron-nucleon scattering experiments conducted between 1967 and 1973 at the Stanford Linear Accelerator Center.
