It was a pioneer initiative in Theoretical Physics, whose aim was to promote research activities and to train young researchers in the area. In the 50's, the institute received several foreign long term visitors, such as Prof. Carl Friedrich Von Weizsacker (first director), Wilhelm Macke and Reinhard Oehme, from the Max Planck Institut fur Physik, Gottingen, Prof. Gert Moliere (also director), Prof. Hans Joos from the Tubingen University and Prof. Werner Guttinger from Aachen, among others. At the end of that decade, Prof. Mituo Taketani from the Rikkyo University, Tokyo, assumed the direction of the institute and brought several Japanese physicists ( e.g. Prof. Yasuhisa Katayama, Tatouki Miyasima, Jun'ichi Osada). In 1958, the Instituto de Ffsica Teorica started to edit the bulletin "Informacao entre Ffsicos" which would give rise to the "Brazilian Journal of Physics". In 1962, Prof. Paulo Leal Ferreira became the first Brazilian director of the institute. After being declared a "Center of Excellence" by the National Research Council (CNPq), the Instituto de Fi'sica Teorica began offering Graduate courses in Physics in 1971, and to this moment more than 50 Ph.D. and 100 Master degrees have been bestowed. In the nation wide rankings of the Brazilian Ministry of Education, the graduate studies program of IFT is considered as one of the best in the nation. In the 80's, after a severe economical crisis, the Instituto de Ffsica Teorica was incorporated to the State University of Sao Paulo (UNESP), as an initiative of its director, Prof. Ruben Aldrovandi. The Foundation still remains as an autonomous entity and maintains the buildings and the library. Nowadays, the Instituto de Fi'sica Teorica is one of the most productive Brazilian research insti- tutions and has scientific collaborations with several international centers. The research subjects include Mathematical Physics, Field Theory, Elementary Particle Phenomenology, Cosmology and Gravitation, Nuclear Physics, Statistical Mechanics, and Nonlinear Dynamics. The scientific staff has 28 researchers and the Graduate course more than 50 students pursuing Master and Ph.D. degrees. 1.2 Research Facilities 1.2.1 Library The Institute has one of the best Brazilian libraries in theoretical physics. It has around 14.000 books covering the areas of mathematics, the physics of elementary particle and fields, nu- clear physics, mathematical physics, cosmology and gravitation, statistical mechanics, condensed matter and atomic physics. It subscribes more than 80 journal titles. 1.2.2 Computing Facilities The Instituto de Fi'sica Teorica has a computer center with a processing capacity of around 100 Mflops. The computing facility includes 1 AXP server, 1 high end server RS6000 IBM, 2 high performance workstations RS6000 IBM, 14 medium performance workstations RS6000 IBM, 15 microcomputers, 12 printers. The local network is linked via TCP/IP and is connected with the international network via BitNet, DecNet, and InterNet. The access to the network is made via X-terminals (NCD). Algebraic software (MathCad, Mathematica, Mapple) and mathematical libraries (IMSL, CERN) besides printing facilities (HP LaserJet IlISi , HP LaserJet ll)are available for the whole network. 1.3 Main Lines of Research 1.3.1 Field Theory Higher spin algebras in conformal field theory, W algebras, conformal field theory and inte- grable models in two dimensions, string field theory, Jacobi equations in field theory, symmetries of Toda models and soliton solutions, field theory in curved space, integration in negative dimensions, causal approach and field theory, constrained dynamics and applications. 1.3.2 Elementary Particle Physics Standard model phenomenology, search for new particles and interactions, alternative models for electroweak interactions, neutrino physics,radiative corrections and precision eletroweak mea- surements, vector boson anomalous couplings, astroparticles, reiativistic hadronic models, phe- nomenology of quark-gluon plasma signatures, instantons and hadronic spectroscopy, two-body reiativistic equations. 1.3.3 Nuclear Physics Nuclear fission, microscopic nuclear models, semiclassical many-body methods, few-body problems, nuclear structure, fusion of heavy ions, electron scattering, giant resonances, restrict dynamic models, nuclear matter at high temperature and densities, hadronic structure, extensions of RPA method, many neutrons nuclei, reiativistic many-body methods, q-deformed algebras and many-body physics. 1.3.4 Gravitation and Cosmology Reiativistic cosmology, quantum gravity, gauge models as alternative theories for gravitation, classical and quantum fields in curved space—time. 1.3.5 Mathematical Methods in Physics Quantum phase spaces, non-commutative geometry in quantum mechanics and many-body systems, quantum groups and invariant forms, quantization structures, singular potentials in quantum mechanics, renormalization in quantum mechanics. 1.3.6 Non—linear Phenomena Integrable models, soliton equations, chaotic dynamical models, Liapunov exponents in hydro- dynamics, Reynolds experiment and turbulence, hierarchy of integrable equations and perturbation theory. 1.3.7 Statistical Mechanics Polymer conformation models, superconductivity at high temperatures, combinatorial meth- ods, quantum groups and critical phenomena. 1.3.8 Atomic Physics Positron-atom scattering at low and medium energies. 2 Personnel 2.1 Faculty Abraham H.

  • Why Antihydrogen and Antimatter Are Different As Paul Dirac Realized, the Existence of Antihydrogen Does Not in Itself Prove the Existence of Antimatter
    ANTIMATTER Why antihydrogen and antimatter are different As Paul Dirac realized, the existence of antihydrogen does not in itself prove the existence of antimatter. A look through the history of the subject, and in particular the role played by the CPT theorem, shows that ultimately it came down to experiment to prove the existence of antimatter through the discovery of the antideuteron at CERN in 1965. “Those who say that antihydrogen is antimatter should realize that we are not made of hydrogen and we drink water, not liquid hydro- gen.” These are words spoken by Paul Dirac to physicists gathered around him after his lecture “My life as a Physicist” at the Ettore Majorana Foundation and Centre for Scientific Culture in Erice in 1981 – 53 years after he had, with a single equation, opened new horizons to human knowledge. To obtain water, hydrogen is, of course, not sufficient; oxygen with a nucleus of eight protons and eight neutrons is also needed. Hydrogen is the only element in the Periodic Table to consist of two charged particles (the electron and the proton) without any role being played by the nuclear forces. These two particles need only electromagnetic glue (the photon) to form the hydrogen atom. The antihydrogen atom needs t wo antipar- ticles (antiproton and antielectron) plus electromagnetic antiglue (antiphoton). Quantum electrodynamics (QED) dictates that the photon and the antiphoton are both eigenstates of the C-operator (see later) and therefore electromagnetic antiglue must exist and act like electromagnetic glue. Dirac surrounded by young physicists in Erice after his lecture “My Life If matter were made with hydrogen, the existence of antimatter as a Physicist”.

  • Dispersion Relations in Gauge Theories with Confinement
    EFI 95-54 MPI-Ph/95-82 Dispersion Relations in Gauge Theories with Confinement 1 Reinhard Oehme Enrico Fermi Institute and Department of Physics University of Chicago, Chicago, Illinois, 60637, USA 2 and Max-Planck-Institut f¨ur Physik - Werner-Heisenberg-Institut - 80805 Munich, Germany Abstract The analytic structure of physical amplitudes is considered for gauge the- ories with confinement of excitations corresponding to the elementary fields. Confinement is defined in terms of the BRST algebra. BRST-invariant, local, composite fields are introduced, which interpolate between physical asymp- totic states. It is shown that the singularities of physical amplitudes are arXiv:hep-th/9511007v1 1 Nov 1995 the same as in an effective theory with only physical fields. In particular, there are no structure singularities (anomalous thresholds) associated with confined constituents, like quarks and gluons. The old proofs of dispersion relations for hadronic amplitudes remain valid in QCD. 1Plenary talk presented at the XVIIIth International Workshop on High Energy Physics and Field Theory, Moscow-Protvino, June 1995. To be published in the Proceedings. 2Permanent Address It is the purpose of this talk, to give a survey of the problems involved in the derivation of analytic properties of physical amplitudes in gauge theories with confinement. This report is restricted to a brief resum´eof the essential points discussed in the talk. 3 Dispersion relations for amplitudes describing reactions between hadrons, and for form factors describing the structure of particles, have long played an important rˆole in particle physics [3, 4, 5, 6]. Analytic properties of Green’s functions are fundamental for proving many important results in quantum field theory.

Ternyata alam tidak seperti demikian. Kekekalan paritas pada interaksi lemah ditumbangkan oleh T.D. Lee dan C.N Yang, serta Wu. Paritas tidak kekal pada semua interaksi lemah termasuk pada peluruhan Λ0 → p+π−. Jika paritas tidak kekal dalam peluruhan Λ, polarisasinya dapat diukur dengan menggunakan proses peluruhan Λ0 → p + π−. Kata kunci: peluruhan, polarisasi. Abstract Parity (P) symmetry was assumed to be conserved in all interactions. If parity were conserved then nature would not have any directional preference. Nature, however, is not so. Conservation of parity in weak interaction had been proven not always true by T.D Lee and C.N.

INTRODUCTION The analytic structure of amplitudes is of considerable importance in all quantum field theories, from a physical as well as a conceptional point of view. It has been studied extensively over many years, but mainly for field theories with a state space of definite metric, and in situations where the in- terpolating Heisenberg fields are closely related to the observable excitations of the theory.
