Neutron Decay

  1. Jan 21, 2009 #1
    Could someone please explain to me why stationary neutrons may radioactively decay but protons may not?

    Thank you in advance :)

    The proton is lighter than the neutron and all other baryons.
    It could only decay into a lighter baryon, but there are none.
    Some speculative theories predict proton decay with a lifetime of the order of the age of the universe, but proton decay has not been observed even at that level.
