We test ArkaniHamed et al.’s dimensional deconstruction on a model that is predicted to have a naturally light composite Higgs boson, i.e., one whose mass M is much less than its binding scale Λ, and whose quartic coupling λ is large, so that its vacuum expectation value v ∼ M / √ λ ≪ Λ also. We consider two different underlying dynamics—UV completions—at the scale Λ for this model. We find that the expectation from dimensional deconstruction is not realized and that low energy details depend crucially on the UV completion. In one case, M ≪ Λ and λ ≪ 1, hence, v ∼ Λ. In the other, λ can be large or small, but then so is M, and v is still

We summarize the general formalism describing surface flows in three–dimensional space in a form which is suitable for various astrophysical applications. We then apply the formalism to the analysis of non–radial perturbations of self–gravitating spherical fluid shells. Spherically symmetric gravitating shells (or bubbles) have been used in numerous model problems especially in general relativity and cosmology. A radially oscillating shell was recently suggested as a model for a variable cosmic object. Within Newtonian gravity we show that self–gravitating static fluid shells are unstable with respect to linear non–radial perturbations. Only shells (bubbles) with a negative mass (or with a charge the repulsion of which is compensated by a tension) are stable.

The nonabelian analog of the LandauPomeranchukMigdal effect is investigated in perturbative QCD. Extending our previous studies, the suppression of induced soft bremsstrahlung due to multiple scatterings of quarks in the spinor representation is considered. The effective formation time of gluon radiation due to the color interference is shown to depend on the color representation of the emitting parton, and an improved formula for the radiative energy loss is derived that interpolates between the factorization and BetheHeitler limits.

Abstract. The star product and Moyal bracket are introduced using the coherent states corresponding to quantum systems with nonlinear spectra. Two kinds of coherent state are considered. The first kind is the set of GazeauKlauder coherent states and the second kind are constructed following the PerelomovKlauder approach. The particular case of the harmonic oscillator is also discussed. (2)

We analyze the initial value problem for spinor fields obeying the Dirac equation, with particular attention to the characteristic surfaces. The standard Cauchy initial value problem for firstorder differential equations is to construct a solution function in a neighborhood of space and time from the values of the function on a selected initial value surface. On the characteristic surfaces the solution function may be discontinuous, so the standard Cauchy construction breaks down. For the Dirac equation, the characteristic surfaces are null surfaces. An alternative version of the initial value problem may be formulated using null surfaces; the initial value data needed differs from that of the standard Cauchy problem. For the case discussed here, the values of separate components of the spinor function on an intersecting pair of null surfaces comprise the necessary initial value data. We present an expression for the construction of a solution from null surface data; two analogues of the quantum mechanical Hamiltonian operator determine the evolution of the system. 2 I.

PROPERTIES OF TOPOLOGIES OF INFORMATION RETRIEVAL SYSTEMS This paper studies topological properties of different topologies that are possible on the space of documents as they are induced by queries in a query space together with a similarity function between queries and documents. The main topologies studied here are the retrieval topology (introduced by Everett and Cater) and the similarity topology [introduced by Egghe and Rousseau). The studied properties are the separation properties To, TI and T2 (Hausdorff), proximity, and connectedness. Full characterizations are given for the diverse topologies to be To, TI or T2. It is shown that the retrieval topology is not necessarily a proximity space while the similarity topology and the pseudometric topology always are proximity spaces. A characterization of connectedness in terms of the Boolean NOToperator is given, hereby showing the intimate relationship between IR and topology.
