For a leptonic weak interaction diagram, we have an election converted into a neutino and emitting a w- particle. But only left handed part should undergo weak interaction. So basically you should have the left handed part of electron converted into a neutrino(left handed) emitting a w- particle. My question is what happens to the right handed part of the election during this interaction? In diagrams that I see in books etc, I don't see the weak interaction diagrams with only left handed part.
Same problem happens for quarks. You have an up quark going to down quark emitting a w+. But shouldn't it be that it is true only for the left handed parts. But from the diagrams it seems to me that the whole up quark is converted to down quark. How can the right handed part of the up quark get converted to the right handed part of the down quark by the weak interaction?
