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 7 '13 at 14:03

This doesn't look like a question... –  Nathaniel Apr 7 '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. –  user1620696 Apr 7 '13 at 14:17

The answer from Mitchell Porter in the -claimed- duplicate question tells most of the history: Han-Nambu solutions. –  arivero Apr 7 '13 at 22:31

1 Answer 1

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

Completely incorrect. The quark charges can be (and have been) measured. –  dmckee Apr 7 '13 at 16:19
