  The title "Time Asymmetric Quantum Theory: the Theory of Resonances" (without
questionmark) of the CFIF workshop (23.-26.7.2003, Lisbon, Portugal) implies
that the theoretical description of resonances is uniquely described by the
formalism of A. Bohm et al. reflecting the title of the workshop. Our
presentation in this workshop tries to introduce an apparently inequivalent,
alternative feasible relativistic formalism provided by the author under the
name "(Anti)Causal Quantum Theory" which is compared to the former.
