  • Particles-Versus-Strings.Pdf
    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.

  • Conformal Symmetry in Field Theory and in Quantum Gravity
    universe Review Conformal Symmetry in Field Theory and in Quantum Gravity Lesław Rachwał Instituto de Física, Universidade de Brasília, Brasília DF 70910-900, Brazil; [email protected] Received: 29 August 2018; Accepted: 9 November 2018; Published: 15 November 2018 Abstract: Conformal symmetry always played an important role in field theory (both quantum and classical) and in gravity. We present construction of quantum conformal gravity and discuss its features regarding scattering amplitudes and quantum effective action. First, the long and complicated story of UV-divergences is recalled. With the development of UV-finite higher derivative (or non-local) gravitational theory, all problems with infinities and spacetime singularities might be completely solved. Moreover, the non-local quantum conformal theory reveals itself to be ghost-free, so the unitarity of the theory should be safe. After the construction of UV-finite theory, we focused on making it manifestly conformally invariant using the dilaton trick. We also argue that in this class of theories conformal anomaly can be taken to vanish by fine-tuning the couplings. As applications of this theory, the constraints of the conformal symmetry on the form of the effective action and on the scattering amplitudes are shown. We also remark about the preservation of the unitarity bound for scattering. Finally, the old model of conformal supergravity by Fradkin and Tseytlin is briefly presented. Keywords: quantum gravity; conformal gravity; quantum field theory; non-local gravity; super- renormalizable gravity; UV-finite gravity; conformal anomaly; scattering amplitudes; conformal symmetry; conformal supergravity 1. Introduction From the beginning of research on theories enjoying invariance under local spacetime-dependent transformations, conformal symmetry played a pivotal role—first introduced by Weyl related changes of meters to measure distances (and also due to relativity changes of periods of clocks to measure time intervals).

  • The Cosmos - Before the Big Bang
    From issue 2601 of New Scientist magazine, 28 April 2007, page 28-33 The cosmos - before the big bang How did the universe begin? The question is as old as humanity. Sure, we know that something like the big bang happened, but the theory doesn't explain some of the most important bits: why it happened, what the conditions were at the time, and other imponderables. Many cosmologists think our standard picture of how the universe came to be is woefully incomplete or even plain wrong, and they have been dreaming up a host of strange alternatives to explain how we got here. For the first time, they are trying to pin down the initial conditions of the big bang. In particular, they want to solve the long-standing mystery of how the universe could have begun in such a well- ordered state, as fundamental physics implies, when it seems utter chaos should have reigned. Several models have emerged that propose intriguing answers to this question. One says the universe began as a dense sea of black holes. Another says the big bang was sparked by a collision between two membranes floating in higher-dimensional space. Yet another says our universe was originally ripped from a larger entity, and that in turn countless baby universes will be born from the wreckage of ours. Crucially, each scenario makes unique and testable predictions; observations coming online in the next few years should help us to decide which, if any, is correct. Not that modelling the origin of the universe is anything new.

  • Weyl Gauge-Vector and Complex Dilaton Scalar for Conformal Symmetry and Its Breaking
    1 Weyl gauge-vector and complex dilaton scalar for conformal symmetry and its breaking Hans C. Ohanian1 Abstract Instead of the scalar “dilaton” field that is usually adopted to construct conformally invariant Lagrangians for gravitation, we here propose a hybrid construction, involving both a complex dilaton scalar and a Weyl gauge- vector, in accord with Weyl’s original concept of a non-Riemannian conformal geometry with a transport law for length and time intervals, for which this gauge vector is required. Such a hybrid construction permits us to avoid the wrong sign of the dilaton kinetic term (the ghost problem) that afflicts the usual construction. The introduction of a Weyl gauge-vector and its interaction with the dilaton also has the collateral benefit of providing an explicit mechanism for spontaneous breaking of the conformal symmetry, whereby the dilaton and the Weyl gauge-vector acquire masses somewhat smaller than mP by the Coleman-Weinberg mechanism. Conformal symmetry breaking is assumed to precede inflation, which occurs later by a separate GUT or electroweak symmetry breaking, as in inflationary models based on the Higgs boson.

  • Conformally Invariant Equations for Graviton 50 5.1 the Conformally Invariant System of Conformal Degree 1
    Conformally Invariant Equations for Graviton Mohsen Fathi Department of Physics, Tehran Central Branch Islamic Azad Univeristy arXiv:1210.3436v3 [physics.gen-ph] 12 Nov 2012 A thesis submitted for the Master degree Master of Science in Physics Tehran, Winter 2010 I am grateful to my supervisor Dr. Mohammad Reza Tanhayi for the helps, supports and scientific training, during this work and thereafter. Abstract Recent astrophysical data indicate that our universe might currently be in a de Sitter (dS) phase. The importance of dS space has been primarily ignited by the study of the inflationary model of the universe and the quantum gravity. As we know Einstein’s theory of gravitation (with a nonzero cosmological constant) can be interpreted as a theory of a metric field; that is, a symmetric tensor field of rank-2 on a fixed de Sitter back- ground. It has been shown the massless spin-2 Fierz-Pauli wave equation (or the linearized Einstein equation) is not conformally invariant. This result is in contrary with what we used to expect for massless theories. In this thesis we obtain conformally invariant wave equation for the massless spin-2 in the dS space. This study is motivated by the belief that confor- mal invariance may be the key to a future theory of quantum gravity.

We prove the consistency of the variational principle and derive the holographic response functions. One of them is the conformal gravity version of the Brown–York stress tensor, the other is a “partially massless response”.

    13 December 2018 Dear Participants: It is my honor to welcome you to the 15th topical physics conference in the “Miami” series --- a meeting that continues a sixth decade of physics conferences held in south Florida. This year’s meeting is dedicated to the memory of Peter Freund. Peter was a good friend to me and many others at this meeting. He was a frequent participant and he gave strong support for these conferences. Moreover, the current particle theory group at the University of Miami was created in the late 1980s largely due to Peter’s enthusiastic endorsement. Before the current series began in December 2004, the “Coral Gables conferences” were organized by University of Miami faculty from January 1964 to December 2003, often assisted by many faculty from other institutions including many of the organizers of this meeting. In particular, Sydney Meshkov has helped to organize and has attended almost all of these meetings since they began over 50 years ago. His participation again this year continues this remarkable tradition. It is also traditional for these meetings to try to accommodate most if not all requests to speak without having parallel sessions. Once again that will be the case, and once again this year the conference program and other useful information will not be printed and distributed in a binder. This information will only be available, in its entirety, online. See https://cgc.physics.miami.edu/Miami2018.html If you must have a printed copy of the entire program, as well as the other useful information, here is a printer friendly source, https://cgc.physics.miami.edu/2018ConferenceBooklet.pdf If you have any special requirements for your talk, or if you have any questions that the hotel staff cannot answer, please ask any attending local member of the organizing committee, in particular, Jo Ann Curtright (cell phone number 786-200-1480), Thomas Curtright (cell phone number 305-793-4637), as well as Diego Castano, and Stephan Mintz.
