Rotation-invariant relations in vector meson decays into fermion pairs
The covariance properties of angular momentum eigenstates imply the existence of a rotation-invariant relation among the parameters of the di-fermion decay distribution of inclusively observed vector mesons. This relation is a generalization of the Lam-Tung identity, a result specic to Drell-Yan pro...
