Relation between jumps at kinematic and anomalous cuts and the $S$-matrix at a mass shell

V. E. Troitsky, Yu. M. Shirokov


Abstract: The jumps at the kinematic and anomalous cuts for the current-operator matrix elements $\langle 2|A(x)|0\rangle$ and $\langle 2|A(x)|2\rangle$ are related to the $S$-matrix at a mass shell.
