The WIN 09 Workshop has been organized by the Laboratori Nazionali del Gran Sasso of INFN and has taken place at the Relais San Clemente near Perugia (Italy) from September 14th to 19th, 2009. At the beginning the Workshop was supposed to be held in the city of L'Aquila, but after the earthquake that affected this region on April 6th, the Organizing Commettee moved the conference venue to the "Relais San Clemente" near the city of Perugia (200 km from L'Aquila).
The philosophy of this small but time-honored series of workshops (it started in the seventies) is to provide the opportunity for the participants to discuss and interact among each other in a very informal and constructive way.
The WIN 09 workshop has featured the following four major topics, discussed in dedicated groups:
First day was for the plenary status reports on the above mentioned major topics. The following days were devoted to working groups on the same major topics. The final plenary sessions have been spent on summaries of the activities of the four working groups given by the leaders of the discussion groups.
