What is the right formalism to search for resonances? II. The pentaquark chain
Abstract We discuss the differences between several partial-wave analysis formalisms used in the construction of three-body decay amplitudes involving fermions. Specifically, we consider the decay $$\Lambda _b \rightarrow \psi \,p K^-$$ Λb→ψpK- , where the hidden charm pentaquark signal has been rep...
