Parity in pion decay

  1. Oct 8, 2005 #1
    Consider this decay:
    Pion+ -> muon+ + neutrino
    It says that one can check the longitudinal polarization of the muon+ and this would confirm that the parity is not conserved. Can you explain what this means in simple terms?

    Where is it stated "longitudinal polarization of the muon+"? Textbook?

    Lets refer to -
    http://hyperphysics.phy-astr.gsu.edu/hbase/particles/piondec.html
    which doesn't answer the question, but is nice background.

    This might explain it -

    and some interesting background "The Failure of Parity in Weak Interactions" by Nick Cowan
    http://www.astro.washington.edu/cowan/school/parity.pdf

    And for additional reading -
