Quarks have the unusual characteristic of having a fractional electric charge. here there is a new model that suggests maybe an up Quark has no electric charge and infact down Quark has electric charge of (+1,-1), through weak interaction between Up Quark and W$^{\pm}$

$$u^{0}+W^{+}\to d^{+},$$ $$u^{0}+W^{-}\to d^{-},$$

sounds like this idea consisted with neutron decay. $$n^{0}\to p^{+}+W^{-},$$ $$u^{0}d^{-}d^{+}\to u^{0}u^{0}d^{+}+W^{-}.$$

This idea that probabilities is associated with unknown parameters is true!, so Quarks fractional electric charge is not accurate value. it is the most probable value
