Calendar of Physics Talks Vienna
| High energy behavior of scattering cross sections |
| Speaker: | Prof. Jnanadeva Maharana (Institute of Physics, Bhubaneswar, Indien) |
| Abstract: | There is a lot of interests in the theories in higher dimesional field theories.
The research activities are spread over topics such as supersymmetry, supergravity
and string theories. It has been argued, since Kaluza and Klein introduced higher
dimensional theory, that the extra dimensions are compactified with very small radius.
Recent years there proposals arguing that the radius of extra dimensions might be large
and the detail phenomenology has been analysed extensively. In this talk, I shall discuss
the analyticity properties of scattering amplitude in higher dimensional field theories in
a formal setting. I shall recapitulate the known rigorous results of analyticity in D=4
theories derived from field theory. I shall briefly discuss possible tests of such ideas at LHC.

| Stationary black holes with matter fields and a negative cosmological constant |
| Speaker: | Piotr T. Chrusciel (Univ. Wien) |
| Abstract: | Im Rahmen des Literaturseminars für Gravitationsphysik: I will show how to construct non-trivial, stationary black hole space-times with
a singularity-free domain of outer communications,, solutions of Einstein-matter
field equations with a negative cosmological constant.
