Our lecturer explained to us that when a stationary Higgs decays into a W+W- pair, which then each decay into an electron/neutrino pair that the electrons will be collimated, however I'm struggling to understand why. He seemed to explain that the leptons would tend to have spin in one direction whilst the neutrinos would have it in the other, and this then causes the leptons to go in the same direction? (Assuming all particles here are massless) However I can't see what would cause this preference in spin direction? If anyone could help explain/point me on the right track I'd be very appreciative thanks!
