In this note we study the tensor and vector exchange contributions to the elastic reactions involving the pseudoscalars mesons \(\pi^+ \pi^-\), \(K^{+}K^{-}\) and \(D^{+}D^{-}\). In the case of the tensor-exchange contributions we assume that an intermediate tensor \(f_2(1270)\) is dynamically gener...
