text: The discovery of charm, bottomness and topness could lead to further expansions up to SU(6) flavour symmetry, which would hold if all six quarks were identical.
text: Problems with particle sizing This neutron structure brings to light certain problems with earlier assumptions about particle sizes: If the electron and down-quark are identical in both charge and size then it should be possible to construct a neutron using two down-quarks.
