Webb1 maj 2011 · The theory of quarks is equivalent to the idea that the down quark has charge -1, the up quark charge +2, and the proton +3. Fractional charges are equivalent to non-fractional charges, simply by multiplication. Quote. It seems that the only thing quarks really have going for them is that lots of people believe in them. 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 …
WebbThe standard model is the name given in the 1970s to a theory of fundamental particles and how they interact. It incorporated all that was known about subatomic particles at the time and predicted the existence of additional particles as well. There are seventeen named particles in the standard model, organized into the chart shown below. WebbQuantum chromodynamics (QCD) The QCD story begins with pions — the force carriers between nucleons — their prediction and discovery. This is then followed by a "particle zoo" that begs for simplification — quarks and gluons are the answer. The strong force vs. the nuclear force a.k.a. the residual strong force.

Webb12 jan. 2024 · There may be beyond-standard-model theories out there that predict sizes for electrons and/or quarks (one might be the Rishon model which all quarks and electrons are composed of three preons; one might be string theory in which rather than fundamental point-like 0-dimensional particles we have vibrating 1D strings), but such theories have …
