Large Deviations from the Polarization-Analyzing Power Equality and Implied Breakdown of Time Reversal Invariance

Abstract

Even though this Symposium brings together a group of researchers active in the field of spin-polarization effects in particle and nuclear physics, I am able to report on evidence that we are, in fact, less “polarized” than some of our presumably “unpolarized” colleagues. I refer to the fact that at last month’s International Conference on Nuclear Physics at Berkeley, my colleague, R. J. Slobodrian, in presenting a report on our work, was prohibited by the chairman of the program committee to use the phrase “breakdown of time-reversal invariance” in his title. It is clear that no such restriction was even considered by the Program Committee of this Symposium.
