Quantum Field Theory in de Sitter space : A survey of recent approaches
Jean-Pierre Gazeau, Marc Lachièze-Rey
We present a survey of rigourous quantization results obtained in recent works on quantum free fields in de Sitter space. For the "massive'' cases which are associated to principal…
Fuzzy de Sitter space-times via coherent states quantization
Jean-Pierre Gazeau, Jihad Mourad, Julien Queva
A construction of the 2d and 4d fuzzy de Sitter hyperboloids is carried out by using a (vector) coherent state quantization. We get a natural discretization of the dS "time" axis b…
Discovery of Very High Energy Gamma-Ray Emission from the BL Lac Object H2356-309 with the H.E.S.S. Cherenkov Telescopes
Aharonian et al.
The extreme synchrotron BL Lac object H2356-309, located at a redshift of z = 0.165, was observed from June to December 2004 with a total exposure of approx. 40 h live-time with th…
MEMPHYS:A large scale water Cerenkov detector at Fréjus
A. de Bellefon, J. Bouchez, J. Busto +12
A water Čerenkov detector project, of megaton scale, to be installed in the Fréjus underground site and dedicated to nucleon decay, neutrinos from supernovae, solar and atmospheric…
Transition from participant to spectator fragmentation in Au+Au reaction between 60 AMeV and 150 AMeV
K. Zbiri, A. LeFèvre, J. Aichelin +28
Using the quantum molecular dynamics approach, we analyze the results of the recent INDRA Au+Au experiments at GSI in the energy range between 60 AMeV and 150 AMeV. It turns out th…
Conformally related massless fields in dS, AdS and Minkowski spaces
E. Huguet, J. Queva, J. Renaud
In this paper we write down the equation for a scalar conformally coupled field simultaneously for de Sitter (dS), anti-de Sitter (AdS) and Minkowski spacetime in d-dimensions. The…
