Theories about quarks
Webb23 dec. 2003 · The theory behind quarks isn't understood well enough to say why up and down quarks behave differently, says Xiangdong Ji of the University of Maryland, College Park. He suspects that's not because the theory is wrong; rather researchers may be misinterpreting it due to the approximations they are forced to use. Related sites … Webb17 jan. 2014 · 17 January, 2014 By Cian O'Luanaigh In 1964, two physicists independently proposed the existence of the subatomic particles known as quarks. Physicists Murray Gell-Mann and George Zweig were working independently on a theory for strong interaction symmetry in particle physics.

Webb27 sep. 1996 · Quantum chromodynamics (QCD) is the field theory of the strong nuclear force, describing, at the fundamental level, the interactions between quarks and gluons. QCD has the property of "asymptotic freedom", which implies that when the quarks and gluons interact at very short distances (distance smaller than about 1/10th fermi or 10 … WebbAs for quarks, they are the fundamental building blocks of a group of particles called hadrons, a group that includes both the proton and the neutron.
