THE WORKSHOP
This will be the fifth of a series of Workshops on High Energy Gamma- ray Experiments, following the Conferences held in Perugia 2003, Bari 2004, Cividale del Friuli 2005, Elba Island 2006.
This year the focus will be on the use of gamma-ray to study the Dark Matter component of the Universe, the origin and propagation of Cosmic Rays, Extra Large Spatial Dimensions and Tests of Lorentz Invariance.
An update on the current and planned research for space-borne and ground-based experiments dedicated to the observation of the gamma-ray sky will be given.
Among the participants there are both hardened veterans of the first dedicated gamma-ray missions (like SAS-2, COS-B, CGRO) and young students entering the fascinating field of gamma-ray astrophysics participating in the new generation of high energy gamma-ray astrophysics experiments like GLAST, AGILE, MAGIC, HESS, ARGO, VERITAS and MILAGRO.
SCIENTIFIC TOPICS
High energy gamma rays give a great chance to study physics beyond the standard model of the fundamental interactions. They are an important probe to better understanding dark matter. Weakly interacting massive particle (WIMP) are the most favorite candidates for dark matter and their nature can be explored studying gamma rays coming from WIMP pair annihilations.
This approach is complementary to the information that will come from the measurement of the antiproton and positron spectrum by the next generation cosmic-ray experiments.
Mapping gamma rays coming from the interaction of primary p and He can also give a deep insight on cosmic-ray production and propagation mechanisms.
Finally many theories of physics beyond the standard model predict the existence of large extra space-time dimensions at an energy scale as low as 1 TeV and a possible high energy break-down of the Lorentz invariance.
The existence of extra dimensions can imply an enhancement of the expected gamma ray flux while a test of the Lorentz invariance can be done through correlated measurements of the difference in the arrival time of gamma-ray photons and neutrinos
emitted from active galactic nuclei or gamma-ray bursts. In this Workshop all these topics will be covered both from the theoretical and experimental point of view.
