    Phases of N=1{\cal N}=1 Theories in 2+1 Dimensions

    We study the dynamics of 2+1 dimensional theories with N=1{\cal N}=1 supersymmetry. In these theories the supersymmetric ground states behave discontinuously at co-dimension one walls in the space of couplings, with new vacua coming in from infinity in field space. We show that the dynamics near these walls is calculable: the two-loop effective potential yields exact results about the ground states near the walls. Far away from the walls the ground states can be inferred by decoupling arguments. In this way, we are able to follow the ground states of N=1{\cal N}=1 theories in 2+1 dimensions and construct the infrared phases of these theories. We study two examples in detail: Adjoint SQCD and SQCD with one fundamental quark. In Adjoint QCD we show that for sufficiently small Chern-Simons level the theory has a non-perturbative metastable supersymmetry-breaking ground state. We also briefly discuss the critical points of this theory. For SQCD with one quark we establish an infrared duality between a U(N)U(N) gauge theory and an SU(N)SU(N) gauge theory. The duality crucially involves the vacua that appear from infinity near the walls.Comment: 53 page

    Electron (positron) beam polarization by Compton scattering on circularly polarized laser photons

    Full text link
    In a number of papers an attractive method of laser polarization of electrons (positrons) at storage rings or linear colliders has been proposed. We show that these suggestions are incorrect and based on errors in simulation of multiple Compton scattering and in calculation of the Compton spin-flip cross sections. We argue that the equilibrium polarization in this method is zero.Comment: 11 pages, LaTeX, talk at 9-th Intern. Workshop on Linear Colliders (LC02), Feb. 4-8, 2002, SLAC, Stanford, US

    The problem of providing an integrated scientific, methodological and information support of the innovation process, covering all its stages including the creative phase, at which novelties are created (solving the problem of conceptual design), is considered. The generic heurorithm (heuristic algorithm) of the innovation management serves as the methodological basis for the implementation of the information support and management innovation system. It is a standard program tool for corporative innovation infrastructure for use in universities, and is intended for describing, accounting and management of ideas at different stages of the innovation cycle. Heurorithm has a modular structure and is represented by a graphical notation systems working schemes. Its schemes reflect a variety of means to support innovation: scientific and methodological support, methods, instructional materials, information resources and a program toolkit (including components of information support and innovation management system). These means correspond to the heuristic components of activities and heuristic information facilities: weakly formalized creative processes and experience gained during their realization. Availability and detailing of heuristics generated and used at different stages of the innovation process for its intensification, is one of the main differences between the developed heurorithm and known organizational charts of innovative activity. On the basis of the generic heurorithm in the system of information support and innovation management an interactive navigator on the stages of the innovation process and means of its support is developed.
