| Abstract: | We estimate the effect of the up and down quark mass difference to the neutron beta decay vector form factor at zero momentum transfer, by using an expansion in chiral SU(3) X SU(3) symmetry breaking to leading order. We find a deviation from a deviation from unity of the order of 3.5X10−5. |
