Radiation Zeros at HERA - More About Nothing

Abstract

The process $eq\to eq+\gamma$ exhibits radiation zeros, i.e. configurations of the final-state particles for which the scattering amplitude vanishes. We study these zeros for both $e^{+}u$ and $e^{+}d$ scattering. The latter exhibits a type of zero which to our knowledge has not previously been identified. The observability of radiation zeros at HERA is discussed.
