The Galileo Galilei Institute (GGI), founded in 2005 by the partnership between the National Institute of Nuclear Physics (INFN) and the University of Florence, has been the first European Institute dedicated to organizing and hosting long-term workshops dedicated to theoretical physics of fundamental interactions. A Launching Committee was appointed to advise about scientific and management structures and suggest criteria for the formation of the Scientific and Advisory Committees. The members of the Launching Committee were David Gross, Giuseppe Marchesini, Alfred Mueller, Giorgio Parisi and Gabriele Veneziano (chair). The GGI was established in a building of the University of Florence on the historic hill of Arcetri, near the house where Galileo spent the last period of his life and died in 1642.

Since 2006 the GGI has been running on average three long-term workshops every year together with conferences and training or focus weeks. In addition, starting from 2013 four PhD schools have been organized every year on different domains of theoretical physics: string theory (this is the pioneering school organized at the GGI since 2008), theory of fundamental interactions, statistical field theory, nuclear and hadronic physics. In 2019 a fifth school on theoretical aspects of astroparticle physics, cosmology and gravitation has been added. Each school lasts two-three weeks during winter and aims at providing lectures on theoretical physics covering both basic as well as advanced topics. The courses of the GGI schools are officially part of the Italian PhD training program for the Universities that join the initiative.

In 2018 the GGI became "Centro Nazionale di Studi Avanzati dell'Istituto Nazionale di Fisica Nucleare" (National Center for Advanced Studies of INFN), once again in partnership with the University of Florence. The Institute thus confirmed its status as a reference point for the international scientific community and as a site dedicated to high-level training of young Italian and foreign researchers. The basic referent of the Center is the INFN National Scientific Committee for Theoretical Physics, which gives its full support to favour the activities of the Institute. Support to its initiatives is also provided by a grant of the Simons Foundation. Workshop proposals, every year, are selected by the GGI Scientific Committee.

Beside its institutional activities, the GGI hosts short term events like conferences, meetings and schools proposed by the international scientific community and selected by the GGI Council. In addition, a long-term visiting scientist program is active. Finally, researchers planning to carry on their research activity at the GGI on a regular basis can apply for the GGI Affiliated Membership.

In 2019, the "Galileo Galilei Medal" award was established. It is assigned every two years to one or more scientists who, in the 25 years before the date of the award, have achieved outstanding results in theoretical physics.

Invited speakers and other contributors to the GGI activities will be equally considered regardless of gender, nationality and ethnic or social origin. The GGI strongly discourage discrimination, harassment and any kind of disrespectful behaviour, actively encouraging friendly and respectful interactions among the participants, and endeavouring to provide a comfortable and professional work environement.

The CDF collaboration of the Tevatron at Fermilab released an important result about W bosons reported yesterday in the journal Science.
The new mass value, determined with a unparalleled level of precision could be a signal of new physics. Giorgio Chiarelli (co-spokesman CDF) and Stefania De Curtis (GGI Director) will discuss it on:
monday 11 April, 18:30.

New opportuniy for you!

The GGI is offering 2 grants (n. 24262/2022) for conducting technological research. These grants are part of the GGPaths project concerning the following topics: planning and organization of collective multidisciplinary outreach events and didactic activities. Creation of a multimedia web-platform in connection with the new scientific paths in Arcetri, from “Villa Galileo” to the GGI. The project is part of Giovanisì - Tuscany Region for the autonomy of young people.
