Proton decay diagram

[1]

Could you add some more explanation to the above diagram? What is U^C? An anti-up quark? An up quark makes more sense.... doesn't it?

Thanks. I did check the original diagram and concluded that a mistake was made in the copying process.[2] Unfortunately I do not have the editing ability to correct the newer diagram. The correction required is either to change U^c to just U, or reverse the direction of the U arrows ( as in the original diagram). --Michael C. Price ^talk 07:00, 18 June 2010 (UTC)[reply]
