Abstract: | The splitting of trajectories with non-vacuum quantum numbers is discussed within the dual unitarisation scheme. The estimated difference in intercepts between vector-tensor trajectories of opposite signatures, such as ? ? A2 and , agrees both in sign and magnitude with that deduced from phenomenological analyses. |
