This paper presents a covariant tensor formalism for partial-wave amplitudes of resonances decaying to four pseudoscalar mesons, covering two-resonance and cascade topologies.
If the difference between intrin- sic spin and the sum of spin resonances is an odd number J12 +J 34 −S= 2m+ 1 the vertex is formed by means of the antisymmetric tensor
