Abstract: | Long ago an unexpected and unexplainable phenomena was observed. The distribution of muons from positive pion decay at rest
was anisotropic with an excess in the backward direction relative to the direction of the proton beam from which it was produced.
Although this effect was observed by several different groups with pions produced by different means and detected by different
methods, the result was not accepted by the physics community, because it is in direct conflict with a large set of other
experiments indicating that the pion is a pseudoscalar particle. It is possible to satisfy both sets of experiments if helicity-zero
vector particles exist and the pion is such a particle. Helicity-zero vector particles have direction but no net spin. For
the neutral pion to be a vector particle requires an additional modification to conventional theory as discussed herein. An
experiment is proposed which can prove that the asymmetry in the distribution of muons from pion decay is a genuine physical
effect because the asymmetry can be modified in a controllable manner. A positive result will also prove that the pion is
not a pseudoscalar particle. |
