Thanks...I understand that... Now, antineutrinos are right-handed...so positrons also will be right-handed in the mass-less limit, since the electrons will be left-handed... It is observed in nature that neutrinos are left-handed and anti-neutrinos are right-handed.. It is also true that...

Hi... I read somewhere that positron, in the massless, limit will have the same helicity as the antineutrino. This must be because they are in the same SU(2) doublet. So helicity operator must commute with the SU(2) generators. Please confirm.
