Free neutrons are unstable, with a half … See moreAlthough it is known that the nucleon is made from three quarks, as of 2006 , it is not known how to solve the equations of motion See more
In the quark model with SU(2) flavour, the two nucleons are part of the ground-state doublet. The proton has quark content of uud, and the neutron, udd. In SU(3) flavour, they are part of the ground-state octet (8) of spin-1/2 baryons, known as the Eightfold way. … See more
