If neutrinos have mass

  1. May 10, 2005 #1
    If neutrinos have mass, can "right-handed" and a "left-handed" change
    to eachother? Why we can only find left-handed ones?

    Thank you.

    Hold on,the antineutrinos are very well "right-handed".I think it's safe to say that explaining preferential chirality of neutrinos (& their antiparticles) is still an enigma within the SM of particles & interactions.

    It is true that a LT can change the helicity of a neutrino with mass (which is usually negative) to positive. The designation LH or RH for particles is used to describe their weak interaction [(V-A) or (V+A)]. In this sense, even a neutrino with mass is LH. The handedness of leptons and quarks is built into the group structure of the Standard Model.

    I see. Thank you.
