Supergravity and Its Legacy Prelude and the Play
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. -
Subnuclear Physics: Past, Present and Future
Subnuclear Physics: Past, Present and Future International Symposium 30 October - 2 November 2011 – The purpose of the Symposium is to discuss the origin, the status and the future of the new frontier of Physics, the Subnuclear World, whose first two hints were discovered in the middle of the last century: the so-called “Strange Particles” and the “Resonance #++”. It took more than two decades to understand the real meaning of these two great discoveries: the existence of the Subnuclear World with regularities, spontaneously plus directly broken Symmetries, and totally unexpected phenomena including the existence of a new fundamental force of Nature, called Quantum ChromoDynamics. In order to reach this new frontier of our knowledge, new Laboratories were established all over the world, in Europe, in USA and in the former Soviet Union, with thousands of physicists, engineers and specialists in the most advanced technologies, engaged in the implementation of new experiments of ever increasing complexity. At present the most advanced Laboratory in the world is CERN where experiments are being performed with the Large Hadron Collider (LHC), the most powerful collider in the world, which is able to reach the highest energies possible in this satellite of the Sun, called Earth. Understanding the laws governing the Space-time intervals in the range of 10-17 cm and 10-23 sec will allow our form of living matter endowed with Reason to open new horizons in our knowledge.

Field Theory Insight from the Ads/CFT Correspondence
Field theory insight from the AdS/CFT correspondence Daniel Z.Freedman1 and Pierre Henry-Labord`ere2 1Department of Mathematics and Center for Theoretical Physics Massachusetts Institute of Technology, Cambridge, MA 01239 E-mail: [email protected] 2LPT-ENS, 24, rue Lhomond F-75231 Paris cedex 05, France E-mail: [email protected] ABSTRACT A survey of ideas, techniques and results from d=5 supergravity for the conformal and mass-perturbed phases of d=4 N =4 Super-Yang-Mills theory. arXiv:hep-th/0011086v2 29 Nov 2000 1 Introduction The AdS/CF T correspondence [1, 20, 11, 12] allows one to calculate quantities of interest in certain d=4 supersymmetric gauge theories using 5 and 10-dimensional supergravity. Mirac- ulously one gets information on a strong coupling limit of the gauge theory– information not otherwise available– from classical supergravity in which calculations are feasible. The prime example of AdS/CF T is the duality between =4 SYM theory and D=10 N Type IIB supergravity. The field theory has the very special property that it is ultraviolet finite and thus conformal invariant. Many years of elegant work on 2-dimensional CF T ′s has taught us that it is useful to consider both the conformal theory and its deformation by relevant operators which changes the long distance behavior and generates a renormalization group flow of the couplings. Analogously, in d=4, one can consider a) the conformal phase of =4 SYM N b) the same theory deformed by adding mass terms to its Lagrangian c) the Coulomb/Higgs phase. -

Twenty Years of the Weyl Anomaly
CTP-TAMU-06/93 Twenty Years of the Weyl Anomaly † M. J. Duff ‡ Center for Theoretical Physics Physics Department Texas A & M University College Station, Texas 77843 ABSTRACT In 1973 two Salam prot´eg´es (Derek Capper and the author) discovered that the conformal invariance under Weyl rescalings of the metric tensor 2 gµν(x) Ω (x)gµν (x) displayed by classical massless field systems in interac- tion with→ gravity no longer survives in the quantum theory. Since then these Weyl anomalies have found a variety of applications in black hole physics, cosmology, string theory and statistical mechanics. We give a nostalgic re- view. arXiv:hep-th/9308075v1 16 Aug 1993 CTP/TAMU-06/93 July 1993 †Talk given at the Salamfest, ICTP, Trieste, March 1993. ‡ Research supported in part by NSF Grant PHY-9106593. When all else fails, you can always tell the truth. Abdus Salam 1 Trieste and Oxford Twenty years ago, Derek Capper and I had embarked on our very first post- docs here in Trieste. We were two Salam students fresh from Imperial College filled with ideas about quantizing the gravitational field: a subject which at the time was pursued only by mad dogs and Englishmen. (My thesis title: Problems in the Classical and Quantum Theories of Gravitation was greeted with hoots of derision when I announced it at the Cargese Summer School en route to Trieste. The work originated with a bet between Abdus Salam and Hermann Bondi about whether you could generate the Schwarzschild solution using Feynman diagrams. You can (and I did) but I never found out if Bondi ever paid up.) Inspired by Salam, Capper and I decided to use the recently discovered dimensional regularization1 to calculate corrections to the graviton propaga- tor from closed loops of massless particles: vectors [1] and spinors [2], the former in collaboration with Leopold Halpern. -

Facing Our Future
ABOUT THE COVER ART Get ready for the end of our world as we know it. How can we not despair at such a prospect? Roll up the sleeves on imagination, compassion, and science and let’s get ready for our new world. The poster for Gustavus Adolphus College’s Nobel Conference “Climate Changed” illustrates some of the solutions for living in a changed climate, as well as the attendant reality of mass migrations. Sharon Stevenson, Designer CLIMATE CHANGEDFACING OUR FUTURE 800 West College Avenue | Saint Peter, MN 56082 | gustavus.edu/nobelconference NOBEL CONFERENCE 55 | SEPTEMBER 24 & 25, 2019 | GUSTAVUS ADOLPHUS COLLEGE NOBEL CONFERENCE 55 I love being in nature, whether it is time at our family cabin WELCOin northern Minnesota, a walk in the Linnaeus Arboretum at ME Gustavus, or the trip I took this summer with my husband to camp and hike in the western national parks. Like many people, I find nature to be a source of renewal, a connection to the Earth and the Divine, and a reminder of the interconnectedness of creation. Also, like many people, I am concerned about our world. As scientific evidence of human-caused climate change is mounting, members of the Gustavus community are working to understand this crisis and its local and Alfred Nobel had a vision of global effects. On campus, several groups are working on this great challenge a better world. He believed of our time. For example, the President’s Environmental Sustainability Council that people were capable of and the student-led Environmental Action Coalition are leading campus initiatives to reduce our helping to improve society campus energy use by 25 percent in the next five years and make improvements in recycling and through knowledge, science, and waste management with the goal of becoming a zero-waste campus, with 90 percent of solid waste humanism. -
