SUMMARY
Neutrinos are inherently left-handed due to their chirality, which is a fundamental property in particle physics. In weak interactions, mediated by the W boson, only left-handed neutrinos participate, while right-handed neutrinos are suppressed by a factor of (1-beta)/2 during decays. This suppression indicates that right-handed neutrinos do not couple with the W boson, reinforcing the dominance of left-handed neutrinos in weak processes. The discussion clarifies that the helicity of neutrinos is not dependent on their mass but rather on their interaction with other particles.
