I was reading the CernCourier, my favorite source of message on Higgs and friends. I was rather shocked, when I saw this:
"The mechanism by which neutrino mass is generated is not known."
What? Not known? Wiki says: In Higgs-based theories, the property of 'mass' is a manifestation of potential energy transferred to particles when they interact ("couple") with the Higgs field, which had contained that mass in the form of energy.
Does this mean that neutrinos don't couple to the Higgs field?
