B) ATTIVITA' PREVISTA PER L'ANNO 2005 The goal of the present research program is to undertake a vast and diversified activity in “Astroparticle Physics”, a recent field of particle physics involving those phenomenological and theoretical aspects of nuclear and subnuclear physics which are relevant for astrophysics and cosmology. This field is in a state of rapid evolution, both for the increased ability in observing phenomena of interest for particle physics and astrophysics, and for the enormous impact on fundamental questions. In particular, almost all the modern indications for new physics and for emerging “new paradigms” (e.g., dark matter and dark energy, neutrino masses, bariogenesis, inflationary models, ultra high energy cosmic rays) find their natural place in the field of astroparticle physics. The fundamental objective is thus to contribute in a qualified and significant way to the scientific development – both theoretical and phenomenological – of this important research field. In this variegated field there is a widely recognized need for a deeper exchange of knowledge and ideas, for a better organized management of the research activity, and for a more effective participation of young researchers and students. The above considerations justify the attempt to form a more solid collaboration among research units that, though belonging to different institutions, have already been engaged for several years in this branch of physics, so as to increase their scientific potential within a common and well formulated research project. It is worth stressing that a large part of the research topics are common to all units, and that a specific collaboration already exists between some of them. It is also worth mentioning that the impressive research activity of the various research units in the last few years is testified by a large number of (often highly cited) publications in leading refereed journals, by many invited talks in major conferences in Italy and abroad, and by the organization of several workshops and schools in astroparticle physics. This deeply−rooted activity provides a solid scientific basis for the research project in astroparticle physics. In the other sections of this document, we describe the main guidelines of the activity currently carried out in the various units belonging to this project. Here we simply idenitify and describe four main topics (A, B, C, D) of major scientific and cultural interest for our project. A) NEUTRINOS IN PHYSICS, ASTROPHYSICS AND COSMOLOGY This field, which is of great interest for all the units, has concerned a large fraction of the total scientific productions from the various groups in the last few years. Results of high relevance have been achieved in the analysis of flavour oscillations and of absolute mass constraints of neutrinos produced in terrestrial or astrophysical environments. This is an extremely wide research field, strongly linked with the other three research topics, and involving many unsolved theoretical problems, as well as many experiments in progress or proposed. Undoubtedly, neutrino physics and astrophysics, both standard (masses and mixings) and nonstandard (new states, new interactions) will continue to be a rich research field in the next years. The following research topics can be sketched: • Solar neutrino physics, stellar astrophysics, and related cross sections • Physics of atmospheric and (long−baseline) accelerator neutrinos • Interpretation of observations of reactor antineutrinos and geoneutrinos • Properties of neutrinos of astrophysical origin (supernovae, nucleosynthesis) • Theoretical aspects of neutrino oscillations in vacuum and matter • Global phenomenological analyses of neutrino oscillations • Absolute neutrino masses: laboratory and cosmological constraints • Theoretical models for neutrino (and other fermion) mass matrices • Open problems: Mass hierarchy, mixing 1−3, CP phase • New physics: sterile neutrinos, magnetic moments, nonstandard interactions B) NUCLEAR AND SUBNUCLEAR PHYSICS IN THE EARLY UNIVERSE Within our project, the study of the behaviour of matter and space−time in the extreme conditions characterizing the early universe has concerned a wide spectrum of important theoretical researches, ranging from string and brane cosmology to the study of hadronic matter in complex and high−density environments, from the cosmological implications of supersymmetry to CP violation effects, from inflationary models to the primordial generation of nuclei, magnetic fields, and possible topological defects. The early universe is – and will continue to be – a privileged laboratory to test the most advanced physical theories of matter and space−time, especially considering the probable observational improvements that can be expected in this field. The main topics are: • String, brane, and extra−dimension cosmology • Extended theories of gravitation and cosmology • Time variation of fundamental parameters • Supersymmetry and its cosmological implications • CP violation, baryogenesis and leptogenesis • Magnetic fields, topological defects, and phase transitions in the early universe • Big bang nucleosynthesis and related cross sections • Compact quark stars, hadronic physics of astrophysical interest C) DARK MATTER, DARK ENERGY AND AND COSMIC STRUCTURES The problems set by the existence of dark matter and dark energy are so important that they have reached the general public. In this field, several units have achieved very relevant results in the theory and phenomenology of the particle candidates of dark matter (neutralinos, WIMPs, baryonic mirror matter), in the dynamical characterization of the possible scalar fields associated to dark energy, and in their links with the formation of large scale structures. In this field, the mere existence of two gigantic unsolved problems (dark matter and

    Particles vs. strings http://insti.physics.sunysb.edu/~siegel/vs.html In light of the huge amount of propaganda and confusion regarding string theory, it might be useful to consider the relative merits of the descriptions of the fundamental constituents of matter as particles or strings. (More-skeptical reviews can be found in my physics parodies.A more technical analysis can be found at "Warren Siegel's research".) Predictability The main problem in high energy theoretical physics today is predictions, especially for quantum gravity and confinement. An important part of predictability is calculability. There are various levels of calculations possible: 1. Existence: proofs of theorems, answers to yes/no questions 2. Qualitative: "hand-waving" results, answers to multiple choice questions 3. Order of magnitude: dimensional analysis arguments, 10? (but beware hidden numbers, like powers of 4π) 4. Constants: generally low-energy results, like ground-state energies 5. Functions: complete results, like scattering probabilities in terms of energy and angle Any but the last level eventually leads to rejection of the theory, although previous levels are acceptable at early stages, as long as progress is encouraging. It is easy to write down the most general theory consistent with special (and for gravity, general) relativity, quantum mechanics, and field theory, but it is too general: The spectrum of particles must be specified, and more coupling constants and varieties of interaction become available as energy increases. The solutions to this problem go by various names -- "unification", "renormalizability", "finiteness", "universality", etc. -- but they are all just different ways to realize the same goal of predictability.

    Supergravity and its Legacy Prelude and the Play Sergio FERRARA (CERN – LNF INFN) Celebrating Supegravity at 40 CERN, June 24 2016 S. Ferrara - CERN, 2016 1 Supergravity as carved on the Iconic Wall at the «Simons Center for Geometry and Physics», Stony Brook S. Ferrara - CERN, 2016 2 Prelude S. Ferrara - CERN, 2016 3 In the early 1970s I was a staff member at the Frascati National Laboratories of CNEN (then the National Nuclear Energy Agency), and with my colleagues Aurelio Grillo and Giorgio Parisi we were investigating, under the leadership of Raoul Gatto (later Professor at the University of Geneva) the consequences of the application of “Conformal Invariance” to Quantum Field Theory (QFT), stimulated by the ongoing Experiments at SLAC where an unexpected Bjorken Scaling was observed in inclusive electron- proton Cross sections, which was suggesting a larger space-time symmetry in processes dominated by short distance physics. In parallel with Alexander Polyakov, at the time in the Soviet Union, we formulated in those days Conformal invariant Operator Product Expansions (OPE) and proposed the “Conformal Bootstrap” as a non-perturbative approach to QFT. S. Ferrara - CERN, 2016 4 Conformal Invariance, OPEs and Conformal Bootstrap has become again a fashionable subject in recent times, because of the introduction of efficient new methods to solve the “Bootstrap Equations” (Riccardo Rattazzi, Slava Rychkov, Erik Tonni, Alessandro Vichi), and mostly because of their role in the AdS/CFT correspondence. The latter, pioneered by Juan Maldacena, Edward Witten, Steve Gubser, Igor Klebanov and Polyakov, can be regarded, to some extent, as one of the great legacies of higher dimensional Supergravity.

  • The Birth of String Theory
    THE BIRTH OF STRING THEORY String theory is currently the best candidate for a unified theory of all forces and all forms of matter in nature. As such, it has become a focal point for physical and philosophical dis- cussions. This unique book explores the history of the theory’s early stages of development, as told by its main protagonists. The book journeys from the first version of the theory (the so-called Dual Resonance Model) in the late 1960s, as an attempt to describe the physics of strong interactions outside the framework of quantum field theory, to its reinterpretation around the mid-1970s as a quantum theory of gravity unified with the other forces, and its successive developments up to the superstring revolution in 1984. Providing important background information to current debates on the theory, this book is essential reading for students and researchers in physics, as well as for historians and philosophers of science. andrea cappelli is a Director of Research at the Istituto Nazionale di Fisica Nucleare, Florence. His research in theoretical physics deals with exact solutions of quantum field theory in low dimensions and their application to condensed matter and statistical physics. elena castellani is an Associate Professor at the Department of Philosophy, Uni- versity of Florence. Her research work has focussed on such issues as symmetry, physical objects, reductionism and emergence, structuralism and realism. filippo colomo is a Researcher at the Istituto Nazionale di Fisica Nucleare, Florence. His research interests lie in integrable models in statistical mechanics and quantum field theory. paolo di vecchia is a Professor of Theoretical Physics at Nordita, Stockholm, and at the Niels Bohr Institute, Copenhagen.

Michel 11, 15121 Alessandria, Italy INFN, Sezione di Torino, via P. Giuria 1, 10125 Torino, Italy Arnold-Regge Center, via P. Giuria 1, 10125 Torino, Italy Abstract We review the group-geometric approach to supergravity theories, in the perspective of recent developments and applications. Usual diffeomorphisms, gauge symmetries and supersymmetries are unified as superdiffeomorphisms in a supergroup manifold. Integration on supermanifolds is briefly revisited, and used as a tool to provide a bridge between component and superspace actions. As an illustration of the constructive techniques, the cases of d = 3; 4 off-shell supergravities and d = 5 Chern-Simons supergravity are discussed in detail. A cursory account of d = 10 + 2 supergravity is also included. We recall a covariant canonical formalism, well adapted to theories described by Lagrangians d-forms, that allows to define a form hamiltonian and to recast constrained hamiltonian systems in a covariant form language. Finally, group geometry and properties of spinors and gamma matrices in d = s + t dimensions are summarized in Appendices. arXiv:1802.03407v5 [hep-th] 16 Nov 2019 Based on lectures given at : the Graduate School of the Physics Dept , W¨urzburg, 2011; Corfu Workshop 2013; LACES 2013, Lezioni Avanzate di Campi e Stringhe, GGI, Flo- rence; CERN-SEENET PhD Training Program, Belgrade, 2015; GGI 2016 Workshop "Supergravity, what next?", Florence.

Schwarz, Harold Brown Professor of Theoretical Physics in the Division of Physics, Mathematics, and Astronomy. Dr. Schwarz majored in mathematics at Harvard (BA, 1962) and then went to UC Berkeley for graduate work in theoretical physics. He offers recollections of his advisor, Geoffrey Chew; working on S-matrix theory; sharing an office with another future string theorist, David J. Gross. After receiving his PhD in 1966, he became an instructor at Princeton, where in 1969 he began work on string theory, prompted by 1968 paper by Gabriele Veneziano. He comments on early years of string theory, his collaboration with André Neveu and Joël Scherk, Murray Gell-Mann’s interest in the work, being denied tenure at Princeton and invited to come to Caltech as a research associate. General lack of interest in string theory in 1970s. Scherk and Schwarz continue working on it and note that the graviton shows up in the theory, suggesting a way to reconcile quantum theory and general relativity; they publish in 1974 and 1975, but papers are largely ignored. In August 1979, he begins collaboration with Michael Green at CERN and later at Caltech and the Aspen Center for Physics. By now there are several string theories, but all are plagued with anomalies; he http://resolver.caltech.edu/CaltechOH:OH_Schwarz_J describes their breakthrough elimination of anomalies in 1984 at Aspen and his announcement of it at the Aspen physics cabaret.

The concept of a “space of quantum field theories” or “theory space” was set out in the 1970’s in work of Wilson, Friedan and others. This structure should play an important role in organizing and classifying QFTs, and in the study of the string landscape, allowing us to say when two theories are connected by finite variations of the couplings or by RG flows, when a sequence of QFTs converges to another QFT, and bounding the amount of information needed to uniquely specify a QFT, enabling us to estimate their number.
