| Abstract: | The spin-1 partner of the goldstino (gravitino) under supersymmetry may be very light and very weakly coupled. We study how it could appear in e+e? annihilations, K and ω decays and beam dump experiments. If its mass is very small it would be produced and interact like a pseudoscalar particle somewhat similar to an axion, but with different decay modes. |
