Quark model Most of the difficulties can be resolved by introduction of a new quantum number called colour. Simela Aslanidou 14.12.2006
Necessity of the colour Quarks are required to be fermions with spin ½ and according to the Pauli principle they cannot occupy the same state. The quantum state has to be antisymmetric with respect to the exchange of all quantum numbers of the quarks. Simela Aslanidou 14.12.2006
