Rätten att söka och åtnjuta asyl har fastställts genom FN:s allmänna förklaring om de mänskliga rättigheterna. Bedömningen av vem som anses vara flykting ska utföras i enlighet med kriterier och normer som återfinns inom internationell såväl som regional och nationell lagstiftning. I asylmål är det inte ovanligt med svårigheter att hitta bevis som styrker den sökandes utsaga. Istället läggs stor v

I den här uppsatsen diskuterar vi flera möjligheter om hur man kan förklara den kosmologiska konstanten. År 1998 genomfördes observationer av typ 1a supernovor som visade att universums expansionshastighet ökar. Det här fenomenet blev kallat mörk energi. Sedan dess har flera olika hypoteser framlagts. Vi ska studera en teori som använder Yang-Mills-fält som en mekanism som hjälper att klargöra fleThe cosmological constant is one of bigger mysteries in modern fundamental physics and cosmology. In this work we investigate one of the possible interpretations for the cosmological constant. The model a studies spatially-homogeneous mode of the Yang-Mills field known as the Yang-Mills condensate and throughout the work we discuss the dynamics and the time evolution of the homogeneous isotropic Y

Bosonic strings can be discretized in terms of dynamically triangulatedrandom surfaces. We investigate the possibility of introducing fermionicdegrees of freedom on the surface in terms of Ising spins, which in twodimensions correspond to Majorana fermions. Critical properties of themodel are estimated using finite-size scaling methods.

Stars ejected from the Galactic Center can be used to place important constraints on the Milky Way potential. We have used Hills stars to constrain models for the Galactic potential, demonstrating that meaningful constraint can be obtained if we have samples of around 50 nearby Hills stars.

Do you have a lot of ideas but nobody and no time to pursue them? Do as Nicole van Der Burg and get an intern through Jobbsprånget ("job leap"). Why did you apply to Jobbsprånget?– As a small lab we have a lot of big ideas with hardly any free time to pursue them, especially with patients sample collection taking up half our week. We knew that if we had a little more time to get some preliminary d

Idag vet man att det finns planeter även utanför vårt solsystem, de snurrar runt sina stjärnor precis som vi snurrar runt Solen - vår stjärna. Man kallar dem `exoplaneter', och hittills har man detekterat över tusen stycken. En del av alla dessa exoplaneter har till synes underliga egenskaper: Deras omloppsbanor är väldigt små, endast några hundradelar av Jordens omloppsbana, samtidigt som de The origin of the class of exoplanets typically referred to as hot Jupiters is to this day an unsettled matter. Some of the proposed formation channels predict certain values of the spin-orbit misalignment parameter, i.e. the angle between the stellar rotation axis, and the angular momentum vector of the planet orbit. One such formation channel is tidal capture following Kozai resonance (TCKR). Th

We construct hadronic potentials that describe the spectrum and decays of electromagnetic bound states of hadrons, and are consistent with Chiral Perturbation Theory. This procedure enables one to clarify the status of the calculations-based on potential models-of the electromagnetic corrections to the observables of hadronic atoms and to the strong scattering amplitudes at low energy.

We find explicit solutions of type IIB string theory on R-4/Z(2) corresponding to the classical geometry of fractional D1-branes. From the supergravity solution obtained, we capture perturbative information about the running of the coupling constant and the metric on the moduli space of N = 4, D = 2 super Yang-Mills.

The Lund dipole model DIPSY is based on BFKL evolution and saturation. It can be applied to collisions between electrons, protons, and nuclei. In this paper, I present some recent results for exclusive final states in inelastic collisions, a method to generate final states in diffractive excitation, and some results for collisions with nuclei.

We report on a search of relations valid at order p(6) in Chiral Perturbation Theory. We have found relations between pi, pi K scattering, K-l4 decays, masses and decay constants and scalar and vector formfactors. In this paper we give the relations and a first numerical check of them.

ColorFull, a C++ package for treating QCD color structure, is presented. ColorFull, which utilizes the trace basis approach, is intended for interfacing with event generators, but can also be used as a stand-alone package for squaring QCD amplitudes, calculating interferences, and describing the effect of gluon emission and gluon exchange.

I present the status of the T(HE)PEG project for creating a common platform for implementing C++ event generators. I also describe briefly the status of the new versions of P-YTHIA, (HERWIG) and A(RIADNE) which are implemented using this framework. (c) 2005 Elsevier B.V. All rights reserved.

If a leptoquark is produced at HERA as a narrow resonance, various effects tend to broaden the measurable mass distribution considerably. These effects are discussed here, with special emphasis on initial- and final-state QCD radiation. A proper understanding is important to assess the significance of data and to devise strategies for better mass reconstruction.

The prospect of experimental verification of the large extra dimension scenario in rare decays is discussed. The case of J/ψ and γ to photon + missing energy is calculated in detail, and it is shown that the limit on the compactification scale MS lies at present in the ten GeV range. In contrast to the quarkonium systems, signals in Kaon and Pion decays will be small.

NLOX is a computer program for calculations in high-energy particle physics. It provides fully renormalized scattering matrix elements in the Standard Model of particle physics, up to one-loop accuracy for all possible coupling-power combinations in the strong and electroweak couplings, and for processes with up to six external particles.

We introduce a method for the separation of soft and collinear logarithms in QCD parton evolution at O(αs2) and at leading color. Using an implementation of the technique in the dire parton shower, we analyze the numerical impact of genuine triple-collinear corrections from quark pair emission in e+e-→ hadrons.
