Rope Hadronization is a model extending the Lund string hadronization model to describe environments with many overlapping strings, such as high multiplicity pp collisions or AA collisions. Including effects of Rope Hadronization drastically improves description of strange/non-strange hadron ratios as function of event multiplicity in all systems from e+e- to AA. Implementation of Rope Hadronizati
We determine the full structure of the leading (double-pole) divergences of O(p6) in the meson sector of chiral perturbation theory. The field theoretic basis for this calculation is described. We then use an extension of this result to determine the p6 contributions containing double chiral logarithms (L2), single logarithms times p4 constants (L × Lr i) and products of two p4 constants (Lr i × L

Using the left-right symmetric model as an illustrative example, we suggest a simple and straightforward way of constraining the W′ mass directly from the decay of the Higgs boson to two photons. The proposed method is generic and applicable to a diverse range of models with a W′-boson that couples to the Standard Model-like Higgs boson. Our analysis exemplifies how the precision measurement of th
High-energy models for πN backward scattering are investigated with respect to consistency with low-energy data using CMSR. As low-energyt-channel input, ππ phase shifts are used below the KK threshold and narrow-width approximations for higher meson poles. Real parts are restricted to appear in thes-channel physical region. A pole model with a double zero in Nα and a « geometrical delta » model r
We discuss our recent results on azimuthal distributions in vector boson + jets and multi-jet production at the LHC, obtained from the matching of next-to-leading order (NLO) perturbative matrix elements with transverse momentum dependent (TMD) parton branching. We present a comparative analysis of boson-jet and jet-jet correlations in the back-to-back region, and a study of the theoretical system
There is a trans-European transport network policy on the supranational level that aims to connect Europe with efficient, sustainable, safe and economically viable cross-national transport infrastructure. Because of this, one could expect EU funding to focus on rail infrastructure, as it has proven to be a low polluting, cost effective and an efficient mode of cross-national transport. However, as
In this thesis we present a method for the calculation of finite volume corrections to the sunset diagram, for arbitrary masses and powers of the propagators. We also present numerical results showing the dependence of these corrections on the volume, which is an exponential decay for large volumes. The results are of high relevance since they can be used in Chiral Perturbation Theory to asses the
The problems of the standard model are reviewed and the motivations for introducing supersymmetry are discussed. The basic theory behind supersymmetry is described briefly, followed by an introduction of two realistic supersymmetric models; the Minimal SuperSymmetric Model (MSSM) and its proposed extension, the NMSSM. Some details of the NMSSM are stated and some constraints on parameters are desc
Utstationering av arbetstagare inom EU är en fråga som diskuterats flitigt de senaste decennierna, inte minst här i Sverige. Uppsatsens syfte är att redo-göra för rättsutvecklingen kring fenomenet både vad gäller unionsnivå och svensk nationell nivå. Uppsatsen presenterar de stora händelserna på området framförallt genom behandling av direktiv, avgöranden från EU-domstolen och den svenska lagstift
This essay intends to map how different values are expressed at different levels of the European trade policy. Prima facie, European trade policy may seem very liberal and as advocating of free trade. This, however, is not entirely true. Within some areas, e.g. agriculture and food policy, EU applies a stricter attitude towards free trade. I believe this to be a consequence of the different priori
Gaia is ESA’s ambitious space astrometry mission with a foreseen launch date in early 2012. Its main objective is to perform a stellar census of the 1000 Million brightest objects in our galaxy (completeness to V=20 mag) from which an astrometric catalog of micro-arcsec level accuracy will be constructed. A key element in this endeavor is the Astrometric Global Iterative Solution (AGIS) - the math
