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

    That's not a reference. This guy cannot even be found on Inspire. – Vibert Apr 07 '13 at 14:03

    This doesn't look like a question... – N. Virgo Apr 07 '13 at 14:09

    But what's your question after all? You want to have any explanation about this? Always make your questions very explicit so that we know what is being really asked. – Gold Apr 07 '13 at 14:17

  • The cross-section for Drell-Yan goes by the $\text{number of colors} \times \sum_\text{accessible mass} \text{squared quark charges}$. It is consistent the standard model a multiple experiments (including one I helped build my first year of experimental work).

    The answer from Mitchell Porter in the -claimed- duplicate question tells most of the history: Han-Nambu solutions. – arivero Apr 07 '13 at 22:31

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
