Charge of a quark

Quark knows content, and it all began with QuarkXPress

A quark is a subatomic particle, so it’s like a proton or a neutron or an electron, that carries a fractional electric charge. What that means is that the overall charge of a quark is not some multiple of the charge of an electron or a proton; it’s different. And in fact, there are two different kinds of fractional charge that a quark can have.Like electrons and other leptons, quarks don't seem to have any structure and appear to be indivisible, as explained by University of Melbourne particle physicist Takaski Kubota in The Conversation.. Quarks are so tiny that it's mind-boggling to even try to express their estimated size. University College London physics professor Jon Butterworth explained that the radius of a quark is roughly ...Oct 21, 2018 · Now I do understand that there could be Baryons made up of four quarks, and they could have then -1/4 and 3/4 charge of the electron's elementary charge. This would work too, and the neutron and proton would have the same way an integer of the electron's charge. So the atom would be stable. We could do this with any integer number of quarks.

Jan 6, 2021 · Mesons are composed of a quark and an anti-quark, so no fractional charge is possible mathematically. Baryons are composed of three quarks, no anti-quarks mixed in with quarks, so no fractional charge is possible. Pentaquarks are composed of four quarks and one antiquark, charge-wise sum of mesons and baryons so no fractional charge is possible. Quarks Table provided on the datasheet. The charge of a hadron is determined by the sum of the charges of its quarks. For example, a proton is made up of two up quarks and a down quark. Adding up their charges gives the charge of a proton: Equivalently, the baryon number and strangeness of a hadron is determined by the sum of the baryon numbers ... Up, charm and top quarks have an electric charge of + 2 / 3, while the down, strange, and bottom quarks have an electric charge of − 1 / 3. Antiquarks have the opposite quantum numbers. Quarks are spin-1 / 2 particles, and thus fermions.
