PREFACE This Conference is 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 was 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.

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 had been covered both from the theoretical and experimental point of view.

An update on the current and planned research for space-borne and ground-based experiments dedicated to the observation of the gamma-ray sky was given with particular enphasis on the succesfull launch of AGILE.

We warmly thank the session chairpersons and all the speakers for their contribution to the scientific success of the Conference.

The Conference was sponsored and supported by the Department of Physics of the University of Roma Tor Vergata, the Italian Istituto Nazionale di Fisica

Nucleare (INFN) Section of Roma Tor Vergata and the National Laboratory of Frascati.

We wish to thank the Organising Committee and International Scientific Advisory Commitee members for their valuable scientific advice and support all along the course of the conference organization.

Special thanks go to all the people involved in the Conference organization: We are particularly grateful to Li Catena and all the Villa Mondragone Staff, Marta Solinas and Gabriella Ardizzoia for their valuable help in preparing and dealing with all the logistics and for the day-by-day assistance at Villa Mondragone and to Vincenzo Buttaro for the creation and updating of the web page.

Finally, our special thank goes to Luigina Invidia, of the Ufficio Pubblicazioni of the Frascati Laboratories, for the technical editing of these Proceedings.
