GGI Lockdown

We regret to inform that schools, workshops, and meetings scheduled to take place at GGI before the 13th of April are cancelled, following the Decree-law 1/04/2020 of the italian Prime Minister that provides indications for dealing with the COVID-19 diffusion. The cancelled events will be re-scheduled according to the organizing committees' requests and to the GGI availability. We apologize for any inconvenience this may cause. Please contact the GGI staff for any further clarification.

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. The first recipient was Juan Martin Maldacena.

Running and next Events
Mar 30, 2020 - May 08, 2020
Emergent Geometries from Strings and Quantum Fields   POSTPONED
The workshop gathers experts on the main geometric structures emerging from string and field theories, in particular: Poisson geometry, noncommutative geometries, generalized geometries and open/closed string inspired (non)geometries, complex and Kaehler geometry, algebraic and super geometry, 3d quantum geometries. It aims at further interconnecting these researches thus paving the way to physical applications.
Topological field theories, T- and U-dualities, supersymmetric field theories, superstrings, string field theory is a non-exhaustive list of topics where these new geometric tools emerged and inspired new directions. The expected outcome is a deeper understanding of the relations between geometry and physics, and ultimately advancements in the quantum structure of spacetime emerging from theories of fields and strings.


30/3: School on Emergent Geometries from Strings and Quantum Fields
6/4: Focus week: Noncommutative Geometry and Algebraic Geometry
13/4: Focus week: Homotopical methods in Quantum Field Theory
20/4: Conference: Geometry of Strings and Fields
27/4: Focus week: Generalized, Higher and Quantum Geometry
4/5: Focus week: Supergeometry and supersymmetry
Apr 06, 2020 - Apr 07, 2020
Mini Workshop
A precise reconstruction and calibration of the jets and of the missing transverse energy (MET) are critical inputs to many Standard Model measurements and new physics searches at the LHC. This workshop, held in the middle of the second long shutdown of the LHC, will review the calibration procedure and the performances of the jet and MET algorithms used in CMS for the analysis of the Run 2 data and discuss preparations and new ideas for the Run 3, focusing in particular on trigger developments and techniques to mitigate the impact of the increased collision pile up.

A special session will also be devoted to preparations for the LHC Phase 2, including new strategies taking advantage of the upgraded detector. The workshop will include an open session with talks from ATLAS and theorists.
Apr 20, 2020 - Apr 24, 2020
Conference on Geometry of Strings and Fields   POSTPONED
May 18, 2020 - Jul 03, 2020
Gravitational scattering, inspiral, and radiation   POSTPONED
The purpose of the workshop is to gather theorists working on apparently different areas which are nevertheless connected to the recent discovery of gravitational waves. More specifically its aims are to: (i) deepen links and foster new collaborations between the quantum gravitational scattering amplitude and the GR community, leading to the calculation of new, high-order, terms in the post-Newtonian and post-Minkowskian perturbative approaches to the physics of binary systems; (ii) identify new synergies between the GR analytical and numerical communities which have already proved to be so crucial in constructing the waveform templates necessary for the analysis of LIGO/Virgo data; (iii) use recent progress on gravitational scattering and radiation in ultra-relativistic collisions of elementary particles or strings to improve the determination of parameters appearing in the effective-one-body approach to the relativistic two-body problem.
This includes profiting from a newly-discovered on-shell construction of gravitational amplitudes from gauge-theory amplitudes; (iv) connect properties of the gravitational wave spectrum at low frequencies to recent developments in soft-graviton theorems at sub- and sub-sub-leading level, including predictions for gravitational memory, BMS asymptotic symmetries, and logarithmic enhancements; (v) explore various consequences of modified gravity theories for the LIGO/Virgo discoveries.
