Discrete ambiguities in a partial-wave analysis of pseudoscalar photoproduction with truncation in total angular momentum

Abstract

The discrete ambiguities appearing in the complete experiment problem for single pseudoscalar meson photoproduction within truncated partial-wave analysis are discussed. It is shown that, in addition to the double ambiguity known from previous works, it is always necessary to take into account another ambiguity arising when truncation in total angular momentum is employed.
