Re: Information on weak charge sought

I read that the W also has weak charge.
So if a virtual W decays into an electron and an antineutrino
the weak charge of the W is transferred to the electron, whereas
the neutrino gets none? Is that correct?

In fact, I see an apparent contradiction between the statement
"all leptons have weak charge" (thus including the neutrino)
and the statement
"the weak charge is proportional to the electric charge"
(which makes the neutrino have a zero weak charge).
Can you (or someone else) clarify this
(and the way weak charge behaves in the W decay)?

Thank you!
