  • Judicial Review of Uncertain Risks in Scientific Research
    Chapter 6 Judicial Review of Uncertain Risks in Scientific Research Eric E. Johnson Abstract It is difficult to neutrally evaluate the risks posed by large-scale leading- edge science experiments. Traditional risk assessment is problematic in this context for multiple reasons. Also, such experiments can be insulated from challenge by manipulating how questions of risk are framed. Yet courts can and must evaluate these risks. In this chapter, I suggest modes of qualitative reasoning to facilitate such evaluation. Keywords Risk · Risk scenarios · Law · Courts · Science · Scientific research · Particle physics · Black holes · LHC 6.1 Introduction In the world of engineering, uncertainty is anathema. Whether designing a nuclear power plant or planning a system of levees, engineers do not like surprises. Exper- imental scientific research, however, thrives on uncertainty. Reaching beyond the current state of knowledge is the whole point of the enterprise. Whether probing the planets or trying to create new particles, scientists would love to see a surprise around every corner. Uncertainty goes hand in hand with aspirations to explore and discover. This special role for uncertainty in scientific research makes questions of catastrophic risk from science experiments particularly interesting. What is more, 1See Hawai‘i County Green Party v.

    SLAC-PUB-3101 April 1983 (T/E) SEARCH FOR SUPERSYMMETRY IN TOPONIUM DECAYS* JOHN ELLIS Stanjord Linear Accelerator Center Stanford Uniueraity, Stanford, California 9@05 and SERGERUDAZ School of Physics and Astronomy University of Minnesota, Minneapolis, Minnesota 55455 ABSTRACT Although cosmology and unification suggest that the mass of the gluino is larger than about 14 GeV, in many theories of broken supersymmetry the photino 5, gluino S and one of the spin-zero partners i of the t quark can be lighter than mt. We calculate Z-T- the decay rates for toponium + 5 S, r 5 and t t and show that in many models they can be as large as, or larger than, the rate for toponium ---, e+e- decay. If it is kinematically accessible, the decay t --* t+q dominates the decays of toponium as well as those of naked top states. Submitted to Physics Letters B * Work supported by the Department of Energy, contracts DEAC03-76SF00515 and DEAC02-83ER40051. One obstacle to the experimental search [l] for supersymmetry (susy) is our the- oretical ignorance about the likely masses of supersymmetric particles. This means that we cannot be sure where susy will first appear, and must plan a broad-band search. The production and detection of supersymmetric particles in hadron-hadron collisions (21, lepton-hadron collisions [3,4] and e+e- annihilation [3,5,6] have been extensively discussed. In the case of e+e- annihilation, there have been discussions of the production of squarks and gluinos in the continuum and of gluinos in heavy quarkonium decays [3,5,6].

What is it trying to tell us? The primary objective of any future collider must surely be to iden- tify physics beyond the Standard Model, and supersymmetry is one of the most studied options. Is supersymmetry waiting for us and, if so, can LHC Run 2 find it? The big surprise from the initial 13-TeV LHC data has been the appearance of a possible signal for a new boson X with a mass ' 750 GeV. What are the prospects for future colliders if the X(750) exists? One of the most intriguing possibilities in electroweak physics would be the discovery of non-perturbative phenomena.

OLIVE ([email protected]) TH Division, CERN, Geneva, Switzerland and Theoretical Physics Institute, University of Minnesota, Minneapolis, MN 55455, USA Received . , accepted . Abstract. Direct and indirect dark matter detection relies on the scattering of the dark matter candidate on nucleons or nuclei. Here, attention is focused on dark matter candidates (neutralinos) predicted in the minimal supersymmetric standard model and its constrained version with universal input soft supersymmetry-breaking masses. Current expectations for elastic scattering cross sections for neutralinos on protons are discussed with particular attention to satisfying all current accelerator constraints as well as insuring a sufficient cosmological relic density to account for the dark matter in the Universe. 1. Introduction Minimal supersymmetric theories with R-parity conservation are particularly at- tractive for the study of dark matter as they predict the existence of a new stable particle which is the lightest R-odd state (the LSP). Furthermore, for parameter values of interest to resolve the gauge hierarchy problem, the LSP has an annihi- arXiv:hep-ph/0106148v1 14 Jun 2001 lation cross section which yields a relic density of cosmological interest (Ellis et al., 1984). Recent accelerator constraints have made a great impact on the available parameter space in the MSSM and in particular the constrained version or CMSSM in which all scalar masses are assumed to be unified at a grand unified scale (Ellis et al., 1998; Ellis et al., 2000a; Ellis et al., 2001b; Ellis, Nanopoulos, & Olive, 2001).

  • Future Perspectives at CERN 3 Unprecedented Accuracy
    Future Perspectives at CERN John Ellis1 Theoretical Physics Division, CERN, Geneva, Switzerland Abstract. Current and future experiments at CERN are reviewed,with emphasis on those relevant to astrophysics and cosmology. These include experiments related to nuclear astrophysics, matter-antimatter asymmetry, dark matter, axions, gravitational waves, cosmic rays, neutrino oscillations, inflation, neutron stars and the quark-gluon plasma. The centrepiece of CERN’s future programme is the LHC, but some ideas for perspectives after the LHC are also presented. CERN-TH/2002-119 astro-ph/0206054 Talk given at the CERN-ESA-ESO Symposium, M¨unchen, April 2002 1 Outline The scientific mission of CERN is to provide Europe with unique accelerators for the study of the fundamental particles of matter and the interactions between them. The scientific programme of CERN for the next decade is centred on the LHC accelerator, which is scheduled for completion in 2006, so that its experi- ments can start taking in 2007. A description of the LHC scientific programme is the centrepiece of this talk. The motivations for this and other new accelera- tors provided by ideas about possible physics beyond the Standard Model were discussed earlier at this meeting [1]. Between now and the startup of the LHC, CERN has a very limited pro- gramme of running experiments. However, scientific diversity at CERN is en- hanced by a number of recognized experiments, that do not use the CERN ac- celerators and are not supported by CERN, but whose scientists are allowed to use other CERN facilities. In parallel with the construction of the LHC, CERN arXiv:astro-ph/0206054v1 4 Jun 2002 is also preparing to send a long-baseline neutrino beam to the Gran Sasso under- ground laboratory in Italy, in a special programme largely supported by extra contributions from interested countries.

THUTOAH investigates the holographic principle and the theory that our universe could be understood as a vast and complex hologram, and hypothesises that, beyond acknowledged art historical contexts and imperatives, artists may have also been unconsciously attempting to describe the holographic nature of the universe. Projecting over 25,000 chronological images from art history (from cave painting to global contemporary art, including outsider and psychedelic art), THUTOAH echoes conceptually the actions of CERN’s particle accelerator, the Large Hadron Collider (LHC), accelerating at 25 images per second in a looped sequence. Alongside this colossal library of images is a soundtrack of interviews with, and watercolours by, the scientists at CERN - illustrations and articulations of the holographic principle.
